What makes biodegradable dry ice blocks different?

Biodegradable dry ice blocks combine ultracold performance with materials designed to break down responsibly. Traditional dry ice comes in pellets or blocks made of solid carbon dioxide; it sublimates at –78.5 °C, لا يترك أي رطوبة. Biodegradable blocks encapsulate the dry ice in a casing made from biodegradable EPS resin that decomposes 92% in four years in a wet landfill environment. The packaging uses plantbased or recyclable films and superabsorbent polymer (النسغ) cells to hold CO₂ pellets. نتيجة ل, you get the same cooling power as standard dry ice without persistent plastic waste.

The environmental benefits are significant. By May 2025, at least twelve U.S. states and two territories had banned expanded polystyrene (EPS) رغوة, spurring demand for biodegradable alternatives. Consumers increasingly judge companies by their environmental practices, so switching to sustainable coolants strengthens your brand.

Performance compared to gel packs and phasechange materials

These blocks deliver subzero temperatures that gel packs and most PCMs cannot achieve. The biodegradable casing gives them a sustainability edge over traditional EPS shells. When selecting a coolant, consider the product’s temperature requirement, transit time and regulatory classification.

Features you should look for

Temperature precision and duration: Aim for blocks that maintain consistent –78.5 °C to –50 °C temperature for 24–72 h. Some highperformance sheets reach 120 h cold duration.

Biodegradability and material safety: The casing should degrade significantly within a few years and comply with foodcontact standards.

سهولة الاستخدام: SAP cells prevent CO₂ pellets from scattering, reducing handling risk. Flexible sheets conform to different box sizes; blocks provide a solid slab for stacking.

دورات إعادة الاستخدام: Highquality products offer more than 100 إعادة استخدام دورات, reducing cost per shipment and waste.

المراقبة الرقمية: Integrated sensors allow realtime temperature tracking, which helps meet Good Distribution Practice (الناتج المحلي الإجمالي) متطلبات.

حالة عملية: A pharmaceutical distributor switched to nanocoated dry ice sheets and, by reusing them over 100 دورات, saved about US$38 000 in annual coolant costs. The same cost efficiencies apply to biodegradable blocks with similar reuse capability.

How to pack medicines using biodegradable dry ice blocks

Stepbystep packing guide

Prepare your medicine: Precondition the medicines to their optimal temperature before packaging. If shipping frozen vaccines, ensure they are at –50 °C or colder to minimize thermal shock.

Choose the right insulated container: Select an insulated foam or biodegradable container validated for dry ice shipping. Avoid airtight glass or plastic containers because sublimation gas can create pressure and cause rupture.

Determine dry ice quantity: Follow the rule of thumb that 5–10 lb (2.3-4.5 كجم) of dry ice will sublimate every 24 ح. For biodegradable blocks, match the block weight to the product weight at a 1:1 ratio and adjust for transit time (12 mm thickness for 24 ح; 18 ملم ل 48 ح; 24 ملم ل 72 ح).

Vent and layer appropriately: Place cushioning at the bottom of the container, then add a separator board. Position the biodegradable dry ice block around or over the product without direct contact to avoid freezing damage. Ensure there is a vent path for CO₂ gas; never seal the container airtight.

Fill voids and secure: Use crumpled paper or biodegradable peanuts to restrict movement. The inner package should be wedged so that when the dry ice sublimates there’s minimal shifting.

التسمية والوثيقة: Mark the box with “Carbon Dioxide, صلب, UN1845" والوزن الصافي للثلج الجاف. ألحق الفصل 9 hazard label on two opposite sides. Include shipper/consignee addresses, and add a note on the airway bill stating “Dry ice, UN1845, net weight X kg” when shipping by air.

خطط للتأخير: Add extra block weight to account for potential delays (another 24 ح). Arrange with carriers for dry ice replenishment if transit extends beyond 72 ح.

Calculating block size and transit time

Choose biodegradable dry ice blocks based on product weight and transit duration. The table below summarizes recommended pairings:

Tips and tricks

Separate items: Use inner boxes or pouches to keep medicines from touching dry ice directly.

تجنب الإفراط في الملء: More dry ice than necessary can freeze products that only need refrigeration. Consider combining smaller blocks with gel packs when shipping goods requiring 2–8 °C.

مراقبة درجة الحرارة: Attach a temperature logger to ensure compliance with GDP requirements. Some biodegradable blocks incorporate RFID sensors for realtime monitoring.

تثقيف الموظفين: Provide training on handling dry ice; it can cause frostbite and burns. استخدم القفازات, goggles and protective clothing.

القضية الفعلية: A field lab transporting blood samples across state lines followed the 1.5:1 ratio for a 48h trip, using biodegradable blocks and a validated cooler. The package arrived with samples still at –70 °C, and no water residue or packaging waste was generated. This practice streamlined compliance and reduced disposal costs.

Understanding regulations and safety requirements

Shipping dry ice is regulated because sublimation gases can displace oxygen and build up pressure. Here are the key rules to follow:

تصنيف المخاطر: يتم تصنيف الثلج الجاف كفئة 9 hazardous material with proper shipping name “Carbon Dioxide, solid” and UN 1845. It is regulated in air and ocean transport but exempt from U.S. ground regulations when packages comply with 49 CFR 173.217.

Package venting: Packages must allow gas to escape to prevent rupture. تجنب الحاويات المغلقة أو محكمة الغلق; use purposebuilt coolers with vent holes or loosely applied tape.

وضع العلامات ووضع العلامات: The outer package must display the proper shipping name, UN number and net weight of dry ice. فئة اللصق 9 hazard labels on two sides and ensure the shipper and consignee addresses are visible.

التوثيق: للنقل الجوي, include a notation “Dry Ice, UN1845, X kg” on the air waybill; a Shipper’s Declaration is not required for nondangerous goods. When dry ice is used to cool dangerous goods, you must prepare a Shipper’s Declaration and include the proper description for each component.

حدود الكمية: تعليمات التعبئة IATA 954 يسمح بما يصل إلى 200 كيلوغرام من الثلج الجاف لكل علبة. Federal guidelines recommend 5–10 lb (2.3-4.5 كجم) من الجليد الجاف لكل 24 ح من العبور.

Training requirements: Staff who handle or prepare dry ice shipments must receive training in hazardous materials handling. IATA and DOT training programs cover proper packaging, وضع العلامات وإجراءات الطوارئ.

ملاحظة السلامة: Dry ice can cause burns and oxygen displacement. Always handle with gloves and never store in airtight containers or confined spaces.
