Mylar Kantong Es Kering: Bagaimana Anda Mengemasnya dengan Aman?
Anda dapat menggunakannya dengan aman jika Anda merancang ventilasi, jarak, dan memperbaiki massa es. Es kering bersuhu −78,5 °C dan berubah menjadi gas; Mylar yang tersegel menjebak gas itu dan bisa meledak. Gunakan jalur ventilasi, pertahankan lipatan yang lembut, dan mengukur es kering dengan aturan sederhana sehingga produk tetap beku dan pengirim tetap patuh.

Apa itu dry ice bag mylar—dan kapan Anda harus menggunakannya?
Gunakan a dry ice bag mylar as a high-barrier liner or sleeve, bukan sebagai ruangan kedap udara. Ini menghalangi bau dan kelembapan, menjaga karton tetap kering, dan melindungi presentasi. Tetapi jika Anda menyegelnya sepenuhnya di sekitar es kering, CO₂ pressure can split the film or seams. Always design a deliberate vent path and place the bag where gas can escape.
Mylar (biaxially oriented PET) shines as a vapor/odor shield and print surface. At deep-cold temperatures it stiffens, so avoid tight creases and crushed corners. For ecommerce frozen food, a hybrid is common: LDPE inside for flex, dry ice bag mylar outside for barrier, both vented.
How does a Mylar dry ice bag behave at −78.5 °C?
Mylar is strong at room temperature and becomes more brittle when very cold, especially at fold lines. Its oxygen and moisture barriers are excellent, but CO₂ must vent. Heat-seals are reliable; untuk es kering, use partial seals, micro-notches, or a membrane patch to release gas in a controlled way.
| Milik (khas) | Mylar (BoPET) | LDPE | Nilon 6 | Apa artinya bagimu |
|---|---|---|---|---|
| Penghalang kelembaban | Tinggi | Sedang | Sedang | Cartons stay drier with Mylar. |
| Oxygen barrier | Tinggi | Rendah | Sedang–Tinggi | Better odor/flavor protection. |
| Flex at −78.5 °C | Moderate–Low | Sedang | Sedang | Avoid sharp creases in Mylar. |
| CO₂ permeability | Rendah | Lebih tinggi | Sedang | Low permeation demands venting. |
| Heat-sealability | Bagus sekali | Bagus | Bagus | Partial/vented seals work best. |
Bagaimana Anda mengemas a dry ice bag mylar to prevent bursts?
The core rule: let CO₂ out. Use a fin-seal notch (2–3mm), 2–4 micro-perforations per 100 cm² on the top panel, or a small breathable membrane patch. Maintain spacer gaps so gas can flow to the cooler headspace and out through a vent crack. Label UN1845 for air, dan hindari wadah kedap udara.
Langkah demi langkah (reliable 36–48 h parcel):
-
Pre-freeze payload ≤ −18 °C; pre-cool shipper.
-
Line shipper; add bottom spacer.
-
Muat produk; Isi kekosongan.
-
Add vented dry ice bag mylar di atas; spread pellets evenly.
-
Add top pad; tutup kapal; keep lid crack/vent.
-
Tandai “Es Kering, UN1845” with net kg; keep package not airtight.

Dry ice bag mylar vs LDPE vs nylon: mana yang harus kamu pilih?
If dryness/odor control is the goal, Pilih A dry ice bag mylar; if flex/fold durability is paramount, LDPE or nylon may be easier. Many teams run hybrids: LDPE inner for flex, dry ice bag mylar outer for barrier. Add a vent path in all cases.
| Gunakan kasing | Best Pick | Mengapa | Alternatif | Catatan praktis |
|---|---|---|---|---|
| Bau & kontrol oksigen | dry ice bag mylar | Superior barrier | Nylon laminate | Keep vent path active. |
| Penanganan yang kasar | LDPE | Lembut, resists cracking | Nilon | Pair with Mylar outer liner. |
| Mixed coolants (PCM + es kering) | Mylar liner + LDPE inner | Penghalang + flex | Coex films | Stabilizes sidewalls. |
| Food contact sleeve | Nylon/PE | Common grades, keras | Mylar/PE | Validate seals. |
What labels and rules apply to dry ice bag mylar di dalam 2025?
Untuk udara, declare “Dry Ice, UN1845” with net kg and ensure packaging can vent CO₂. Keep packages not airtight. Post clear handling icons, and train teams to use PPE and ventilate workspaces. Untuk tanah, follow carrier guidance; same venting and labeling discipline reduces returns and safety incidents.
2025 tren membentuk dry ice bag mylar and frozen shipping
Expect vent-friendly laminates, membrane vents, and smarter SOPs. Teams are standardizing vent notches and pre-sealed patches, adding QR-coded instructions, and adopting recyclable mono-material structures. Hybrid coolant strategies (PCMS + es kering) are rising to buffer temperature extremes while preserving unboxing quality.

FAQ
Bisakah saya menyegel a dry ice bag mylar completely airtight?
TIDAK. Airtight sealing traps CO₂ and can cause a burst. Add a notch, kinerja mikro, or a membrane vent.
Where should the bag sit—top or bottom?
Top is safer. CO₂ tenggelam; top placement vents gas and avoids direct freeze shock.
How many perforations are safe?
As few as needed—often 2–4 per 100 cm² on the top panel only. Over-perforation defeats barrier benefits.
Why does Mylar crack at deep-cold temps?
It stiffens at −78.5 °C, and sharp folds create stress risers. Sudut bulat, avoid tight pleats, choose thicker gauges.
Can I mix PCMs with dry ice inside a dry ice bag mylar sistem?
Ya. Place PCMs around sides and the vented Mylar dry ice pouch on top to avoid product over-freezing.
Ringkasan & Langkah selanjutnya
Kunci takeaways: Gunakan ventilasi dry ice bag mylar as a barrier liner, top-place it with spacers, es kering ukuran yang tepat dengan kalkulator, and standardize labeling and PPE. Hybrids with LDPE boost durability; validation beats guesswork every time.
Lakukan ini selanjutnya:
-
Pick your vent method and bag gauge.
-
Run a 48-hour pilot with a data logger.
-
Adjust dry-ice mass using real lane data.
-
Publish a one-page SOP with photos.
-
Train the bench; audit monthly.
