Frozen Barrier Material Selector
Select high-performance laminates engineered for extreme sub-zero stability. Our films prevent crystal formation and maintain flexibility even at -40°C.
BOPA (Nylon) Composite
BOPA / LLDPE
Essential for frozen seafood and bone-in meats. The BOPA (Nylon) layer provides exceptional puncture resistance and gas barrier properties at low temperatures.
High Impact & Puncture Strength
High-Barrier Vacuum
PET / PA / PE
Multi-layer co-extrusion designed for vacuum sealing. Effectively eliminates freezer burn by creating a skin-tight oxygen barrier that locks in natural juices.
Zero-Leakage Vacuum Integrity
Recyclable Mono-PE
PE / EVOH / PE
A circular economy solution for frozen produce. Uses EVOH for freshness while remaining fully recyclable within the PE stream.
100% Recyclable Architecture
Anti-Static IQF Poly
PE / LLDPE (Co-ex)
Optimized for Individually Quick Frozen (IQF) lines. Anti-static and anti-slip additives ensure fast, jam-free packing of frozen fruits and vegetables.

Sub-Zero Integrity.
Arctic Precision.
Our frozen food packaging systems are tested under extreme conditions. We simulate the rigors of the cold supply chain—from blast freezing to long-haul refrigerated transit—ensuring no brittle cracking or seal failure occurs.
Freezer Burn Analysis
We provide WVTR analysis at freezing points to ensure your product retains 99.9% moisture throughout its shelf life.
Steam-Vent Technology
Custom laser-perforated films for frozen ready-meals, allowing for safe steam release during microwave heating.
Crystal-Clear Anti-Fog
Specialized surface treatments ensure windows remain free of condensation and ice crystals for high-visibility retail.
Frozen Logistics
Technical FAQ.
Protecting frozen assets requires more than a standard pouch. It demands fracture-resistant polymers, hermetic seals, and anti-frost clarity—engineered for the harshest cold chains.
"Precision at Absolute Zero"
Industrial Grade Frozen Food Solutions
How do you prevent bags from becoming brittle and cracking?
🧊Standard plastics fail at sub-zero temperatures. We incorporate high-percentage Metallocene and BOPA (Nylon) resins which maintain high elongation and impact strength even at -40°C, preventing "cold-crack" during transit.
Are these films suitable for rapid blast-freezing?
⚡Yes. Our films are engineered to handle the rapid thermal contraction of blast freezing. The high-performance adhesive systems ensure that laminate layers do not delaminate when moving from ambient to arctic conditions.
Do you offer "Steam-in-Bag" microwaveable options?
🍲We offer specialized RCPP (Retort Cast Polypropylene) structures with laser-venting. This allows consumers to take the product directly from the freezer to the microwave, with controlled pressure release for perfect steaming.
Solving the Realities of
Cold-Chain Distribution
Frozen food faces unique retail pressures. Condensation, ice crystals, and rough handling can destroy shelf appeal. At Sengelin, we provide the technical expertise to ensure your product survives the freezer and thrives on the shelf.
"Ice crystals are obscuring our product through the window."
Fluctuating temperatures cause condensation and frost. We apply advanced anti-fog coatings to our high-clarity PET windows, ensuring a crystal-clear view of your product even in humid freezer displays.
"Sharp frozen items like shrimp are puncturing our bags."
IQF (Individually Quick Frozen) items become hard as rock. Our co-extruded Nylon/PE films offer superior puncture resistance and flex-crack stability to prevent micro-leaks that cause dehydration and freezer burn.
"Seals are failing during the expansion of frozen liquid."
Liquids expand as they freeze. We utilize heavy-duty sealant layers with a wide seal-window, providing the burst strength necessary to accommodate volume changes without compromising the package integrity.
