There are many types of vacuum bags for selecting food packaging bags, which can be divided into industrial packaging and food packaging. The product specifications required for food vacuum bags are significantly higher than those for general industrial products. When selecting food vacuum bags correctly, what aspects should be taken into consideration? The outer packaging of food packaging bags should have Chinese markings, indicating the factory name, address, and product name, and clearly indicating the words "for food use".

After the product leaves the factory, it is accompanied by a product inspection certificate. Food packaging bags used for food are odorless and odorless when leaving the factory. Food packaging bags with special odors cannot be used for food packaging. Colored food packaging bags (dark red or black colors used in the market at that time) cannot be used for food packaging. Because these types of food packaging bags are often made of recycled plastic.

Try to choose materials that are not coated or plated. In modern packaging planning, many materials with coatings are used to make the packaging more beautiful and corrosion-resistant. This not only poses difficulties for the recycling and reuse of materials after product obsolescence, but most coatings themselves are toxic. Assuming that people consume these packaged foods, it will cause significant harm to their bodies.

In addition, the coating and plating processes have also brought great pollution to the environment. For example, toxic solvent gases are evaporated from coatings, and wastewater containing heavy metals such as chromium and slag pollution are generated during electroplating. Therefore, packaging materials that are not coated or plated should be chosen as much as possible. It is better to choose food and buy it at large shopping malls, rather than at street stalls.

Due to the non degradable nature of food packaging bags, they can cause environmental pollution. Therefore, when purchasing food, it is advisable to choose green packaging materials. Paper is a widely used green packaging material nowadays. So, when choosing food, it is advisable to choose original paper packaging, as well as biodegradable plastics.
