Refrigerated eye drops need a medicine packout that protects the approved handling range, the secondary carton, the pharmacy label, and the receiving decision. The correct range must come from the product label, manufacturer instructions, pharmacy SOP, and the customer’s quality agreement.
This guide uses a refrigerated medicine route as the planning model. The shipper should not be treated as a simple cooler. It must be tested with the actual product mass, carton count, coolant conditioning, route duration, handoff time, and seasonal ambient profile.
Packout planning data
Temperature range
Commonly 2-8 C for products labeled refrigerated; always follow the approved label and dispensing instructions.
Humidity and condensation
Protect paper cartons, patient instructions, and pharmacy labels from condensation.
Pre-cooling
Pre-condition shipper and coolant so the small product mass does not sit next to overly cold packs.
Package pressure
Use small-product inserts so bottles and cartons do not shift, crush, or press against coolant.
Coolant position
Use conditioned gel packs with corrugate, foam, or molded dividers between coolant and cartons.
Transport duration
24-48 h parcel or pharmacy routes should be tested because small cartons warm and cool quickly.
Tempk small-medicine shipper, 2-8 C coolant spacing, carton insert, dry label protection, and temperature logger.
What changes for this product
Refrigerated eye drops can fail for reasons that are not visible from the outside carton. A product may arrive apparently cold while one layer has touched a frozen pack, or cartons may be wet enough that labels and instructions become hard to verify. Small medicine packs also move quickly with ambient changes, so logger position and coolant spacing matter.
Pre-conditioning should happen before loading. If the shipper, coolant, or staging area starts outside the target profile, the first hours of transit can create a freeze or warm excursion. For refrigerated medicines, hard coolant contact is one of the most common avoidable risks.
Recommended Tempk packaging approach
Use a Tempk 2-8 C insulated shipper or insulated liner with conditioned gel packs, a validated product barrier, carton or vial support, and continuous monitoring when the lane requires documented release. Small orders should use an insert so medicine cartons stay in the tested product zone rather than sliding toward coolant.
For high-value or patient-critical shipments, add a receiving checklist that covers logger status, product count, label dryness, visible damage, and quarantine instructions. This helps the receiver make a clear release decision instead of guessing from carton touch temperature.
Receiving checks
At receiving, the team should review the logger result before placing stock into usable inventory. If the product label, SOP, or quality agreement defines an excursion process, the shipment should be held until the responsible pharmacist or quality team completes that review.
Tempk can support shipper sizing, coolant map design, insert layout, and route validation. Share product carton dimensions, order quantity, target range, route duration, ambient profile, and release procedure to build a lane-specific packout.

Sous-Vide Meals Cold Chain Packaging Guide
Sous-Vide Meals Cold Chain Packaging Guide
Sous-vide meals need a chilled packout that protects food safety, texture, label condition, and receiving decisions at the same time. A generic cold box can hold temperature in a short test but still fail commercially if sauces leak, cartons become wet, pouches are punctured, or the top layer warms during courier dwell.
For planning, this guide uses a chilled 0-4 C lane because many prepared food programs target refrigerator temperature before retail, catering, or direct-to-consumer handoff. The final accepted range should always follow the product specification, HACCP plan, local food rules, and the receiving customer’s quality agreement.
Packout planning data
Temperature range
0-4 C for chilled cook-chill distribution; freezing may damage texture, purge control, and pouch presentation.
Humidity and condensation
Protect outer labels and case markings from condensation on vacuum pouches.
Pre-cooling
Verify the cook-chill process and hold product at the approved chilled range before packing.
Package pressure
Avoid sharp carton edges, hard coolant contact, and over-tight packing that can puncture or crease vacuum pouches.
Coolant position
Place gel packs outside an inner carton or smooth liner so pouches do not contact frozen or rough surfaces.
Transport duration
24-48 h restaurant, retail, or subscription routes need validation with real pouch counts and coolant mass.
Common losses
Seal creep, pouch puncture, purge, frozen edges, condensation, warm top layer, and delayed release decisions.
Tempk packaging fit
Tempk insulated shipper, smooth inner carton, conditioned gel packs, pouch divider, and logger positioned in the product zone.
What changes for this product
Sous-vide meals should not be packed only by carton size. The packaging should be designed around product mass, headspace, water activity, seal type, and the way the customer opens or stages the food. The cooling system must keep the product below the approved limit without creating frozen contact points that damage texture or presentation.
Pre-cooling is especially important. If warm product, warm sauce cups, or recently filled pouches enter the shipper, gel packs are forced to remove product heat instead of protecting the route. That shortens hold time and increases the chance of a warm receiving result even when the outside carton looks acceptable.
Recommended Tempk packaging approach
For routine lanes, use a Tempk insulated box liner or insulated shipper with conditioned gel packs, a smooth inner carton or product tray, and a logger placed in a representative product zone. For heavier loads or long courier dwell, validate the coolant mass and shipper size with summer and winter profiles rather than relying on a single ambient test.
Coolant should be separated from delicate food packs. This protects film seals, paper labels, clamshell lids, vacuum pouches, and bread or pasta texture. Where leakage is possible, add an absorbent layer or secondary bag that contains liquid without blocking cold airflow around the product.
Receiving checks
At arrival, the receiving team should check logger data, carton dryness, seal condition, product shape, and visible leakage before releasing stock. If the logger shows an unresolved excursion or the carton is saturated, the shipment should be held according to the customer’s quality procedure.
Tempk can support shipper sizing, gel pack placement, route testing, and packout instructions for chilled prepared food programs. Share the product dimensions, order quantity, target range, route duration, ambient profile, and receiving procedure to build a lane-specific packout.
Chilled Soups Cold Chain Packaging Guide
Chilled Soups Cold Chain Packaging Guide
Chilled soups need a chilled packout that protects food safety, texture, label condition, and receiving decisions at the same time.

The final accepted range should always follow the product specification, HACCP plan, local food rules, and the receiving customer’s quality agreement.
Packout planning data
Temperature range
0-4 C for chilled soup distribution; avoid freezing when texture, cream separation, or container stress is a concern.
Humidity and condensation
Use carton protection and absorbent control because soup packs can create heavy condensation.
Pre-cooling
Only load fully chilled product; do not rely on the shipper to remove residual cooking heat.
Package pressure
Keep cups, tubs, pouches, and lids upright and supported so seals are not stressed in transit.
Coolant position
Use conditioned gel packs around the load with upright dividers and a barrier from thin pouch walls.
Transport duration
24-36 h is common for local or regional chilled soup lanes; 48 h routes need lane testing.
Common losses
Leaks, swollen lids, carton saturation, warm center temperature, label damage, and flavor or texture separation.

Humidity and condensation
Control condensation so paper sleeves, ingredient labels, and reheating instructions stay readable.
Pre-cooling
Pre-chill filled trays, sauces, garnish packs, and shipper components before packing.
Package pressure
Protect ravioli, filled pasta, film-sealed trays, and sauce cups from compression and corner impact.
Coolant position
Place conditioned gel packs above and beside the load with a liner or carton barrier, not directly against delicate trays.
Transport duration
24-48 h direct-to-store, catering, or DTC routes should include pickup dwell and receiving delay.
Common losses
Warm top layer, condensation, sauce cup leaks, film seal lift, pasta texture softening, and crushed trays.
Tempk packaging fit
Tempk insulated shipper or box liner, conditioned gel packs, tray-level dividers, absorbent layer when needed, and route logger.
What changes for this product

Pneumococcal Vaccines Cold Chain Packaging Guide
Pneumococcal vaccines require a cold chain plan that follows the product label, local health authority rules, and the shipper’s validated SOP. The packaging should protect the approved temperature range, vial condition, label readability, and receiving release decision.
Pneumococcal vaccine shipments often move in small, high-value clinic replenishment orders where every carton must remain traceable.
The packout should reduce both freeze risk and top-layer warming risk during courier dwell.
Receiving checks should confirm the logger result before product is returned to inventory.
Cold chain planning data
Temperature window
Commonly 2-8 C and protected from freezing; always follow the product package insert.
Humidity or moisture
Keep cartons and vial labels dry, especially for clinic replenishment shipments with small order quantities.
Pre-cooling
Pre-condition the shipper and coolant so the load starts within the validated 2-8 C range.
Packaging pressure
Protect single-dose boxes and vials from hard coolant contact and carton compression.
Coolant placement
Use conditioned gel packs or phase-change material with a validated barrier between coolant and vaccine cartons.
Transit duration
24-48 h routes should include courier dwell and receiving appointment timing.
Common losses
Freeze excursion, warm top layer, wet cartons, crushed cartons, delayed receiving, and stock quarantine.
Suitable Tempk packout
Tempk clinic replenishment shipper with 2-8 C coolant map, dry label protection, vial support, and continuous logger.
Recommended packout approach
Start with product that is already within the approved storage range. Condition the shipper and coolant before loading, use a barrier between coolant and product cartons, and place the temperature logger in a representative product zone rather than directly against coolant.
For refrigerated vaccines, the main packaging risk is often freeze exposure from poorly conditioned gel packs. For frozen or ultra-low temperature programs, dry ice mass, ventilation, carrier rules, replenishment timing, and logger placement require a separate validation plan.
Quality checks before release
Before commercial use, test the actual carton size, product load, coolant mass, route length, ambient season, and receiving window. At arrival, check temperature data, carton dryness, label condition, vial movement, coolant condition, and any product-specific excursion instructions.
Tempk can support 2-8 C, frozen, or dry ice-compatible packout planning, but final release decisions should always follow the vaccine manufacturer’s instructions and the customer’s quality system.
Reference basis
Temperature guidance is based on CDC vaccine storage and handling resources and WHO vaccine cold chain practice. Always confirm the current package insert before shipment.
Rabies Vaccines Cold Chain Packaging Guide
Rabies vaccines require a cold chain plan that follows the product label, local health authority rules, and the shipper’s validated SOP. The packaging should protect the approved temperature range, vial condition, label readability, and receiving release decision.
Rabies vaccines are often time-sensitive, so the packout should make receiving checks fast and unambiguous.
If a product includes diluent, the packout and documentation should keep vaccine, diluent, and instructions together.
Freeze protection is critical whenever conditioned gel packs sit close to vials in a small shipper.
Cold chain planning data
Temperature window
Commonly 2-8 C; always follow the manufacturer package insert for vaccine and diluent handling.
Humidity or moisture
Control condensation so vial labels, diluent cartons, and instructions remain legible.
Pre-cooling
Pre-condition shipper and coolant to a stable 2-8 C profile before loading vaccines and diluent.
Packaging pressure
Use vial support and inner cartons so vials do not contact hard gel packs or move during transit.
Coolant placement
Use conditioned gel packs or phase-change packs separated from vials by corrugate, foam, or a validated insert.
Transit duration
24-48 h is common for replenishment routes; emergency lanes need validated fast handoff and receiving checks.

COVID-19 Vaccines Cold Chain Packaging Guide
COVID-19 vaccines require a cold chain plan that follows the product label, local health authority rules, and the shipper’s validated SOP. The packaging should protect the approved temperature range, vial condition, label readability, and receiving release decision.
COVID-19 vaccine programs should not use a generic vaccine box without checking the current product label and local health authority instructions.
Some routes may need refrigerated handling, while others may involve frozen or dry ice logistics. These are separate packout validations.
The receiving team should know how to read the logger, inspect shipper condition, and quarantine product if the approved range is not confirmed.
Cold chain planning data
Temperature window
Product-specific: refrigerated, frozen, or ultra-low temperature requirements depend on manufacturer labeling.
Humidity or moisture
Keep cartons dry and protect vial trays, labels, and secondary packaging from condensation.
Pre-cooling
Condition the shipper, coolant, data logger, and staging area to the product's approved range before loading.
Packaging pressure
Protect vial trays and cartons from hard coolant, dry ice blocks, and vibration during parcel or validated courier transport.
Coolant placement
Use gel packs, phase-change material, frozen packs, or dry ice only when the product label, SOP, and carrier rules allow it.
Transit duration
Validate each route by product, shipper size, coolant mass, replenishment plan, and delivery window.
Common losses
Temperature excursion, dry ice depletion, condensation, label damage, vial tray movement, and quarantine at receiving.
Suitable Tempk packout
Tempk validated insulated shipper, product-specific coolant map, continuous temperature logger, and receiving excursion workflow.
Recommended packout approach
Start with product that is already within the approved storage range. Condition the shipper and coolant before loading, use a barrier between coolant and product cartons, and place the temperature logger in a representative product zone rather than directly against coolant.

Premium Fruit Gift Boxes Cold Chain Packaging Guide
Premium fruit gift boxes need e-commerce cold chain packaging that protects product condition after parcel sorting, courier dwell, and doorstep waiting time. The right packout should be validated around the actual product mix, coolant mass, route duration, and receiving behavior.
Premium fruit gift boxes are judged by presentation as much as temperature.
The packout must hold a cool range while preventing gel pack marks, wet decorative boxes, and fruit movement.
Route validation should include opening appearance, bruise check, condensation check, and temperature data.
Cold chain planning data
Temperature window
2-8 C for many premium chilled fruit gift programs; avoid freezing contact on delicate fruit.
Humidity or moisture
Control condensation so gift packaging, sleeves, and labels stay clean and presentable.
Pre-cooling
Pre-cool fruit and packaging components gradually to avoid surface condensation before packing.
Packaging pressure
Use trays, cavities, or pads to prevent bruising during parcel drops and side pressure.
Coolant placement
Place gel packs in separated zones, away from direct contact with fruit skin and decorative packaging.
Transit duration
24-48 h is preferred for premium gift boxes; 72 h lanes need stronger testing for bruising and condensation.
Tempk insulated shipper with molded fruit support, separated gel packs, moisture barrier, and arrival-quality checklist.
Recommended packout approach
Start with products that are already at their dispatch temperature. Use an insulated shipper or liner, a documented gel pack map, and internal separation so cold mass controls heat gain without damaging labels, fruit, produce, or ready-to-eat items.
For mixed e-commerce orders, separate raw protein from ready-to-eat products, isolate wet coolant from paper packaging, and validate the top layer because parcel cartons often fail first near the lid. If frozen items are included, build a separate frozen packout rather than combining chilled and frozen assumptions.
Quality checks before release
Before scale-up, run a route test using the same carton size, product weight, coolant count, courier service, season, and doorstep dwell. At arrival, check temperature, carton dryness, product appearance, label condition, leakage, odor, and whether the customer-facing presentation still matches brand expectations.
For Tempk packaging selection, the usual starting point is an insulated liner or EPS shipper, separated gel packs, inner dividers, and a route logger. The final design should be adjusted after validation rather than copied from a generic parcel box.
Reference basis
Temperature assumptions are aligned with FDA guidance for keeping refrigerated foods at 40 F / 4 C or below and FDA meal kit receiving guidance. Final programs should follow the shipper’s product specifications and the destination market’s food safety expectations.
Online grocery chilled orders need e-commerce cold chain packaging that protects product condition after parcel sorting, courier dwell, and doorstep waiting time. The right packout should be validated around the actual product mix, coolant mass, route duration, and receiving behavior.
Online grocery orders combine products that fail in different ways, so one cold pack position rarely protects the whole carton.
Raw protein should be isolated from ready-to-eat items, produce should be protected from freezing contact, and dairy should arrive cold without wet labels.
The validation plan should include doorstep dwell because e-commerce orders are not always received immediately.
Cold chain planning data
Temperature window
0-4 C for chilled perishables; frozen SKUs should be packed and validated separately.
Humidity or moisture
Keep outer cartons dry and separate wet gel packs from labels, paper bags, and produce packaging.
Pre-cooling
Pre-cool chilled groceries, gel packs, insulated liners, and staging totes before order assembly.
Packaging pressure
Protect soft produce, dairy tubs, and ready-to-eat packs from heavy meat, beverages, and gel packs.
Coolant placement
Place gel packs near top and sidewall heat gain, separated from delicate produce and paper labels.
Transit duration
Same-day to 48 h lanes are common; unattended doorstep time should be included in validation.
Common losses
Warm top layer, wet labels, bruised produce, dairy sweating, meat leakage, and mixed-carton odor transfer.
Suitable Tempk packout
Tempk insulated liner or box with gel pack map, inner dividers, absorbent base for raw protein, and delivery-time validation.
Recommended packout approach
