Transparent plastic packaging is cheap and convenient clear bags with poly material, which can be printed logo and used in clothing items, face masks, etc. And, we pack all the products in a transparent, odorless bag. So, it just has the right size, but the quality is unclear.
A survey shows, at present, the world’s food packaging safety and health qualified rate only reached more than 60%. But, the main reason is the improper selection of raw materials. When you buy plastic bags, be sure to look carefully. Besides, don’t misuse recycled plastic bags. So today, I will explain how to judge whether the transparent plastic packaging bag is qualified.
According to the data, many plastic bags on the market have two types of plastic film:
One consists of non-toxic and safe raw materials. Such as polyethylene and polypropylene that meet national standards. Hence, we can use such plastic bags to hold food.
The other is the recycling of waste plastics, recycled plastics. And other toxic and unsafe materials. We decompose them with temperature changes and other reasons to produce toxic and harmful substances.
In general, we can make a simple distinction from the following aspects:
First is the color of transparent plastic packaging
Safe and healthy transparent plastic packaging bags have the natural color and good transparency.
Then the texture of transparent plastic packaging
The quality of safe and healthy plastic bags is even and not easy to be damaged. The surface of recycled plastic bags is unevenly stretched. And they contain fine particles and impurities. So, it is easy to be damaged.
The third is to smell
Safe and hygienic plastic packaging bags are tasteless. But waste recycled plastic bags have irritating odors or abnormal aromas.
Finally, see the recycling logo
According to the national standard, the packaging materials can mark with “recyclable and renewable”. And the coding of different plastic marks can mark in the center of the graph. So, it is helpful to facilitate recycling and reuse after waste.
