At present, the common pet food packaging bags on the market are plastic flexible packaging, composite plastic packaging, paper-plastic packaging, aluminum-plastic packaging and tinplate packaging cans. Regardless of the packaging form, packaging integrity is the primary requirement for packaging quality. If there are small cracks or holes in the packaging, oxygen and water vapor in the air will enter the packaging through these gaps, and pet food will undoubtedly be prone to mold and deterioration. Generally speaking, the integrity of the packaging is easy to appear in the heat sealing part of the packaging bag, the lid of the packaging can and other material docking parts.
