What are the uses of biodegradable packaging bags? Do you know all this

1. Physical maintenance. The food stored in the packaging bag needs to be prevented from kneading, collision, feeling, temperature difference and other phenomena.

2. Shell maintenance. The shell can separate food from oxygen, water vapor, stains, etc. Leakproofing is also a necessary element of packaging planning. Some packages include desiccants or deoxidizers to extend shelf life. Vacuum packaging or removing air from degradable packaging bags are also the main food packaging methods. Keeping food clean, fresh and safe during the shelf life is the main function of the packaging bag.

3. Pack or put in the same package. Packing small objects of the same kind into a package is a good way to save volume. Powder and granular objects need to be packaged.

4. Convey information. Packaging and labels tell people how to use, transport, recycle, or dispose of packaging or food.

5. Marketing. Marketing often uses box labels to encourage potential buyers to buy products. For decades, packaging planning has become an irrelevant and constantly changing phenomenon. Marketing communication and graphic planning should be applied to the highlights and sales of the outer box (for some reason).

6. Security. Packaging can play an important role in reducing transportation safety risks. Packaging bags can also prevent food from returning to other products. The degradable packaging bag can prevent food from being illegally eaten. Some food packaging is very strong and has anti-counterfeiting signs, the effect of which is to protect the interests of enterprises from being lost. It has laser marking, special color, SMS authentication and other labels. In addition, in order to prevent theft, retailers put electronic surveillance tags on the bags and wait for consumers to take them to the outlet of the store for demagnetization.

7. Convenience. Packaging can be easily purchased, loaded and unloaded, stacked, displayed, sold, opened, repackaged, applied and reused.

There are currently three so-called environmentally friendly plastic bags: degradable plastic bags, biodegradable plastic bags, and compostable plastic bags. Everyone thinks that biodegradability means biodegradation, but it is not. Only if it can be decomposed into carbon dioxide and water can it protect the environment. To buy a biodegradable or compostable plastic bag, you need to check whether the bag is issued with a plastic bag label specified by the country. According to the label, determine the production materials. The commonly used biodegradable or compostable materials are PLA and PBAT. Biodegradable bags are in It can be degraded into water and carbon dioxide in 180 days under the conditions of nature and soil or industrial compost, which belongs to the organic cycle and is harmless to the human body and the natural environment.
