Coffee is a drink that most young people like now, so what kind of packaging material is suitable for customized Coffee packaging bags? If the customized Coffee packaging bags is made of material with low gas barrier, even if it is tightly sealed, the aroma of the coffee will permeate. If such a packaging material is used, oxygen, water vapor and various other gases in the air will also penetrate. If you plan to store it for a long time, you must choose a package with high gas barrier properties. Even if the correct packaging method is used, if the packaging material is not selected properly, the internal environment of the customized Coffee packaging bags cannot be maintained for a long time, then everything that has been done before is meaningless.

In the past, most of the coffee products were canned. In recent years, the market has developed rapidly, and plastic packaging bags have appeared to replace traditional cans. The accompanying problem is how to bond films of various properties together to produce high-quality customized Coffee packaging bags. The construction of most films is as follows: the outside is high-strength polyester or nylon, and the inside is heat-melting, easy-to-bond polyethylene. The interlayer in the middle is a film with high insulating properties such as aluminum foil, polyester aluminized film, and ethylene-vinyl alcohol copolymer.
Each layer of film is glued together by pressing, and sometimes it will smell of residues such as glue and adhesive. Due to the difference in shape and material, it will also be difficult to fit, so special attention should be paid to the selection and processing of materials.
