冷凍食品向け軟包装ソリューション
Frozen Food Packaging Material Options
Recommended material structures for frozen food packaging: NY/PE offers excellent low-temperature toughness and puncture resistance, suitable for frozen meat, seafood and vegetables; PET/PE provides good printing surface and sealing strength for general frozen products; PET/AL/PE is suitable for long-shelf-life frozen products requiring moisture and oxidation protection; BOPP/CPP works for lightweight frozen snacks. The frozen-grade PE layer should maintain performance at -18C to -40C without brittleness. Thickness typically recommended at 80-120 microns depending on product weight, shape and transport conditions.
Recommended Packaging Types for Frozen Food
- Food Packaging Roll Film — for VFFS/HFFS automatic packing of frozen vegetables, fruit and seafood
- Three Side Seal Pouches — for frozen single-serve portions and snacks
- Stand Up Zipper Pouches — for retail display of frozen fruit, vegetables and snacks
- Retort Pouches — for frozen ready meals requiring sterilization before freezing
Quality Control Points for Frozen Food Packaging
Quality control points specific to frozen food packaging: low-temperature heat seal strength testing (at -18C), frozen-state drop testing, puncture resistance testing (simulating sharp edges of frozen products), moisture barrier testing (WVTR), seal integrity testing (dye penetration method), cold impact testing (rapid temperature change from ambient to -40C). Retained samples from each production batch for traceability.
What to Prepare Before Inquiry
- Product type and freezing temperature range
- Bag size or roll film width
- Whether puncture-resistant structure is needed
- Shelf life and storage conditions
- Packing machine type (VFFS/HFFS/manual)
- Estimated order quantity
- Printing colors and artwork file
- Destination country or region
材料の提案
Material recommendations by product type: dry products typically use PET/PE or BOPP/CPP; oily or high-aroma products benefit from PET/VMPET/PE or PET/AL/PE for better barrier; liquids and sauces need NY/PE or PET/AL/PE for chemical resistance and leak-proof sealing; frozen products use cold-resistant PE layer; high-temperature sterilization uses PET/AL/CPP or PET/AL/PA/CPP retort-grade structures. Huasheng Packaging recommends suitable structures based on specific product type and shelf life requirements.
