Manufacturer of octagonal sealed packaging bags

In order to provide some help to everyone, I will explain in detail today the method of selecting octagonal sealing bags and the selection and application of various materials.

1. The inner layer material of octagonal sealed packaging bags produced by major manufacturers is PE, also known as polyethylene, which is recognized as the best material in contact with food in the world. It is non-toxic, odorless, and odorless, and meets the hygiene standards for composite food packaging. PE film is lightweight and transparent, with characteristics such as moisture resistance, oxidation resistance, acid resistance, alkali resistance, and good heat sealing performance.

2. The outer layer material of octagonal sealed packaging bags is generally PET. PET film has good transparency, good strength, hardness, non-toxic, flame retardant, organic solvent resistance, oil resistance, and other characteristics. Due to the fact that PET film does not have a heat sealing type, it is used as the outer layer material of octagonal sealed packaging bags.

3. In octagonal sealing bags, some businesses prefer to use aluminum foil. The quality of octagonal sealing bags with aluminum foil is better, and aluminum foil film is added to the inner layer. Some people may ask, aluminum foil is hard metal and easy to rot. Is it suitable for use in packaging bags? In fact, we can rest assured that the aluminum foil used in packaging bags is a very thin layer of aluminum foil film. Although aluminum foil is easy to rot, it becomes very strong when combined with PET and PE. At this time, the various advantages of aluminum foil bags are highlighted. The produced aluminum foil octagonal sealing bags not only have good light proof effect but also have good moisture proof effect.

Based on the above three points, we know that there are actually two types of octagonal sealing bags according to the material. One is a two-layer, pure plastic octagonal sealing bag, and the other is a three-layer, aluminum foil octagonal sealing bag. If your product is packaged with a weight of less than 500 grams and is not prone to moisture and deterioration, you can use a two-layer octagonal sealing bag. If your product is packaged with a weight of more than 500 grams and is prone to moisture and deterioration, We suggest you choose a three-layer aluminum foil bag.
