As an environmentally friendly and degradable packaging material, paper bags have been widely used in the food packaging industry due to their excellent performance. However, the safety of paper bags in food packaging is crucial and directly affects the health of consumers and the quality of food.

Importance of material selection
Food-grade materials
In the field of food packaging, the material selection of paper bags is a key factor in ensuring safety. Food-grade paper bags usually use non-toxic and harmless raw materials, including food-grade paper and environmentally friendly inks. Strictly tested food-grade materials ensure that they will not cause contamination to food during use.
Non-toxicity: The raw materials must not contain harmful substances, such as heavy metals, plasticizers, and organic solvents, to prevent harmful substances from migrating into food during the packaging process.
Moisture and oil resistance: Food packaging paper bags must have good moisture and oil resistance to effectively protect the quality of food and extend its shelf life.
Application of composite materials
In some cases, a single paper material may not meet the needs of specific food packaging, so composite materials (such as a combination of paper and plastic) are widely used. This type of composite material not only enhances the strength and durability of paper bags, but also provides superior moisture and oil resistance, ensuring the safety of food during transportation and storage.

Strict control of the production process

Hygiene management

In the production process of paper bags, strict hygiene management is an important part of ensuring food safety. Manufacturers must follow good manufacturing practices (GMP) to ensure the cleanliness of the production environment and the hygiene of equipment.

Clean environment: The production workshop should be kept highly clean and disinfected regularly to prevent microbial contamination and ensure that the production environment meets food safety standards.

Employee hygiene: Production personnel need to receive systematic training to ensure that hygiene standards are followed during the production process, such as wearing gloves and masks, etc., to avoid contamination caused by human factors.

Quality control system

Establishing a sound quality control system is an important measure to ensure the safety of paper bags. Manufacturers need to strictly monitor every production link, including raw material procurement, production process and finished product testing.

Raw material testing: Strict quality testing of all raw materials to ensure that they meet relevant food safety standards and avoid the use of unqualified materials.
Finished product testing: Conduct comprehensive physical and chemical performance testing on finished paper bags to ensure that they meet relevant food packaging standards and ensure the safety and reliability of the final product.
