How to Choose the Thickness of Packaging Bags

The thickness of the packaging bag should be selected based on the weight of the packaged item. For heavier items, a thicker bag is required. Generally, products weighing less than 100g can use a 4-micron-thick bag; products between 100-500g are recommended to use a 5-6-micron-thick bag; products between 500-1000g should use a 7-8-micron-thick bag; and items exceeding 1000g require a bag thicker than 10 microns. This ensures the bag does not rupture or damage during transportation and storage due to excessive weight. However, this standard is not absolute and should be determined based on actual conditions.

Select based on the dimensions of the packaging

The thickness of the packaging bag should also be selected based on the size of the packaged item. For items with larger dimensions and a strong three-dimensional appearance, it is recommended to use relatively thicker packaging bags to ensure they can withstand greater pressure and friction, preventing breakage or wear during use. Special considerations should be made for items with unique properties, such as fragile or sharp objects, which require packaging bags with sufficient cushioning and puncture resistance, potentially necessitating thicker material layers. Products like powders or liquids demand higher requirements for sealing and leak-proofing, possibly requiring thicker inner layers or additional leak-proof barriers. For items sensitive to environmental factors (e.g., oxygen, moisture, light), such as food and pharmaceuticals, composite materials with excellent barrier properties should be chosen, and thicker barrier layers may be necessary.
