Vacuum packaging is one of the most effective packaging methods for extending product shelf life, reducing package volume, and protecting products during storage and transportation. Plastic vacuum bags are widely used in the food industry, medical products, industrial components, and pet food packaging because they provide reliable sealing performance and excellent barrier properties.
