1. Plastic Packaging for Frozen & Chilled Foods
Technical Requirements:
- Oxygen & moisture barrier to preserve flavor, color, and nutrition.
- Withstand deep-freeze conditions without cracking.
- Food-safe, non-toxic, compliant with hygiene standards.
- Compatible with vacuum sealing and automated lines.
Recommended Material: PA/PE (Nylon/Polyethylene).
- PA (Nylon): High puncture resistance, tensile strength, reduced tearing during stacking, moderate oxygen barrier.
- PE (Polyethylene): Chemically inert, food-safe, strong heat-sealing, flexible at -18 °C or below.
Applications: Vacuum seafood bags, frozen meat packs.
Benefits: Prevent freezer burn, extend freshness, adaptable to vacuum or semi/fully automatic packing lines.
2. Retort Packaging for High-Temperature Sterilization (121–135 °C)
Technical Requirements:
- Withstand retort process (115–135 °C, 30–90 minutes).
- Strong oxygen & moisture barrier, often with AL or EVOH layers.
- No chemical migration at high temperature.
- Resistant to delamination, mechanical stress, and pressure.
Recommended Materials:
- PET/AL/CPP
- PET/NY/CPP
- PET/PA/CPP
- PET/EVOH/CPP
Material Functions:
- PET: Printability, mechanical strength.
- AL or NY: Oxygen & light barrier, preserve flavor.
- CPP: Heat resistance, sealing.
- PA: Transparency, puncture resistance (alternative to AL).
- EVOH: Transparent, superior oxygen barrier.
Applications: Soups, curries, porridges, ready-to-eat meals.
Benefits: Replace metal cans, lower logistics costs, retain nutrients, suitable for automatic/semi-automatic machines.
3. Vacuum Packaging for Long-Term Shelf Life
Technical Requirements:
- Near-zero oxygen permeability.
- Strong puncture resistance.
- Leak-proof heat seals.
- Food-safe and stable.
Recommended Material: PA/EVOH/PE
- EVOH: Exceptional oxygen barrier.
- PA: Mechanical strength, puncture resistance.
- PE: Safe contact layer, good sealability, deep-freeze compatible.
Applications: Sausages, cheese, premium dry goods.
Benefits: Extend shelf life, prevent oxidation, preserve flavor.
4. Snack & Dry Food Packaging
Technical Requirements:
- Moisture & oxygen protection to maintain crispness.
- Light barrier for fried snacks.
- Attractive, glossy print surface.
- Moderate mechanical strength.
Recommended Materials:
- OPP/CPP → for short shelf life, fast consumption.
- OPP/MPET/CPP → for oily, long-life snacks.
Material Properties:
- OPP: Glossy, printable, moisture barrier.
- Metalized PET: Enhanced gas barrier, light protection.
- CPP: Strong heat seal.
Applications: Confectionery, instant noodles, chips.
Benefits: Eye-catching appearance, maintain crunch, resist humidity.
5. Packaging for Sauces, Oils, and Liquid Condiments
Technical Requirements:
- Oxygen & moisture barrier against rancidity.
- Light resistance to protect color and flavor.
- High mechanical durability.
- Leak-proof sealing.
- Food-safe under heat treatment.
Recommended Materials:
- PET/AL/PE → For oil-rich sauces and long shelf life.
- PET/NY/PE → For flexible, liquid pouches.
Applications: Ready-to-use sauce sachets, oil pouches.
Benefits: Safer than glass bottles, lightweight for transport.
