Packaging for food | Transparent packaging for food | Clear food packaging

1. According to the shape, characteristics, transportation environment, sales environment and other factors of the goods, packaging for food uses appropriate packaging materials, designs a reasonable packaging structure, and protects the goods.

2. In the design of packaging for food packaging, not only the physical, acid, and alkali chemical forces of the packaging machinery on the packaging material, but also the packaging materials that can withstand these external forces to protect the contents should be selected. 
It is also necessary to consider the damage caused to the contents due to shaking, sudden braking, bumps, drops, etc. in the process of commodity circulation, so as to take appropriate measures to strengthen the strength of the packaging.

3. Storage stacking will make the container and contents in the lower part of the stack bear a great weight. In order to prevent damage to the packaging container or inner packaging, the pressure resistance of the packaging structure must be considered.

4. Accommodating goods is an aspect of packaging protection. Gaseous, liquid, powder and loose articles cannot be transported and sold without packaging.
Therefore, the packaging material should be able to resist the chemical corrosion of the contents. For example, some detergents of shampoo can cause environmental stress cracking of polyethylene bottles or delamination of composite films. Isopropyl myristate contained in some cosmetics may soften polystyrene, etc.
Also consider chemical and dust pollution from the outside.
Sometimes it not only contaminates the product itself, but also contaminates the patterns and containers of the packaging itself.

5. The protective functions of packaging also include protection against corrosion, moisture, water, shock, shock, breakage, pollution, volatilization, bacteria, light, oxidation, heat or freezing.
Some anti-theft covers for outer packaging such as boxes, barrels, and cans are used not only to seal and prevent leakage, but also to prevent theft or poisoning in circulation.

6. For those products of special nature, special packaging should be used, with special marks and explanatory text.
This is conducive to the safe storage, transportation, loading and unloading and use, ensuring the safety of people and creatures.

Packaging for food is normally produced by material PET, PP, PS or food grade PVC etc
