Plastic packaging bags used for food packaging are in direct contact with food, and their hygienic and safety are extremely important. The following are the main hygienic and safety standards for this type of packaging bag.
First of all, in terms of raw materials, strict requirements must be met. Plastics used for food packaging should be non-toxic and odorless. For example, materials such as polyethylene and polypropylene are widely used in food packaging bags because they are chemically stable and not easy to react with food to produce harmful substances. It is strictly forbidden to use plastic raw materials containing heavy metals, plasticizers and other substances that are harmful to the human body.
From the production process point of view, the entire process should be ensured to be clean and pollution-free. The production workshop must meet certain hygiene standards to prevent dust, bacteria and other contamination of the packaging bag. In the printing process, the ink used must be food grade and must not contain solvents and pigments that are harmful to the human body. At the same time, no harmful substances that may migrate to food should be added during the production process.
In terms of physical properties, the packaging bag should have a certain strength and sealing to prevent food from being contaminated by the outside world during transportation and storage. For example, good tear strength can prevent the packaging bag from being accidentally scratched, while reliable heat sealing performance can ensure that the packaging bag is tightly sealed to prevent the intrusion of oxygen, water vapor and microorganisms.
For the detection of hygiene indicators, microbial detection and chemical residue detection are usually included. Microbial detection mainly checks whether there are harmful bacteria, molds and other microorganisms on the surface of the packaging bag. Chemical residue detection is to detect whether the packaging bag contains harmful substances that may migrate into the food, such as heavy metals, plasticizers, organic solvents, etc.
In addition, plastic packaging bags for food packaging should also comply with relevant national standards and regulations. These standards and regulations have clear provisions on the materials, production processes, and hygiene indicators of packaging bags to ensure the food safety of consumers.
In short, the hygiene and safety standards of plastic packaging bags for food packaging cover multiple aspects such as raw materials, production processes, physical properties and hygiene indicator detection. Only by strictly complying with these standards can we provide safe and reliable packaging for food and protect the health of consumers.
