Food Packaging

The packaging of consumed foods can be divided into convenient food, puffed food, pastries & biscuit, dairy product & baked goods, candy & preserved fruit, meat product, pre-made food, roasted nuts, frozen food,health care, grain & oil, sauce, wine & beverage, tea & instant drink etc.

Convenience Foods

1. Types of Food

Instant Noodles, Mixed Sauce Noodles, Hot and Sour Noodles, Rice noodles, Red Oil noodles, small noodles, Dry Bibimbap, Latiao, Vermicelli, Crispy Noodles, Seaweed, Self-healing Pot etc.

2. Packaging Requirements

(1) High Oxygen Barrier/High Moisture Barrier: The fats and oils in food would be easily oxidized and deterioration, resulting in bad smell and taste, decreasing its nutritional value. So the packaging must be high oxygen barrier. The dry and crispy food has low water content, and it is easy to be damp and decrease in crispiness. What��s more, the the increase of water content would accelerated the fats and oils oxidation. So it is required a packaging with high moisture barrier to keep the food dry and inhibit the microbial proliferation.

(2) High Heat Sealability: The food packaging is required high heat separability because the food crumb, fats and oils would pollute the heat seal interface and affect the sealing strength.

(3) Good Sealing: If the packaging pouch is broken or there��s a gap in the heal seal, the water and oxygen would seep into the pouch, resulting in food spoilage.

(4) High Impact Strength: The packaging pouch would be broken, especially heal seal broken, when a fall occurs. So the packaging film is required high impact strength to prevent the damage in transportation and storage.

(5) High Peeling Strength: The peeling strength between the laminate layers is low, even delaminated, which would weaken the material integration of all layers, such as heal-sealing strength, tensile strength and impact strength etc. Easily result in poor use when the packaging suffers external force.

(6) Low Residual Solvent: The residual solvent in the packaging film may be slowly seep into the food, so we must minimize the residual solvent in food packaging as possible as we can.

(7) Suitable Right Angle Tearing:It is easy to tear the pouch when use, easy to eat.

(8) High Puncture Resistance: There may be sharp objects inside the convenience food packaging. The packaging pouch will be punctured easily during transportation, resulting in food spoilage. So the packaging must be high puncture resistance.
