What are the requirements for food packaging bags?

The requirements for food packaging bags primarily include material safety, packaging design, production standards, usage limitations, and environmental protection requirements. Material safety: Food packaging bags must use non-toxic, clean materials, such as food-grade plastics, to ensure that harmful substances do not precipitate and contaminate food. Ordinary PE plastic bags are not suitable for storing hot food or meat because their heat resistance is not strong, and they may expand and decompose upon contact with fats and oils.

How to ensure the safety of food packaging bags

The key to ensuring the safety of food packaging bags lies in selecting appropriate materials, employing strict production processes, and adhering to standards. First, the choice of food packaging bag materials is crucial. Common safe materials include high-performance plastic films such as polyethylene (PE) and polypropylene (PP), as well as paper, cardboard, and aluminum foil. These materials have good sealing, moisture-proof, and barrier properties, effectively protecting food quality and safety. In addition, with the increasing awareness of environmental protection, more and more food packaging bags use biodegradable or recyclable materials, such as bio-based plastics and PLA (polylactic acid), to reduce their impact on the environment.

How to seal food packaging bags

Folding method: Lay the bag flat, fold the opening down 3-4 times, then fold the sides inward slightly, then turn it over and pinch it, finally straighten the bag. Straw sealing method: Use two straws of the same size, cut one vertically, roll up the other with the bag opening, then place the cut straw on top to seal the bag opening. Heat sealing method: Flatten the bag opening, wrap a magnetic strip card around the bag opening, then heat it with a lighter nearby, and continue to move the card position to seal it.
