Product type
Vacuum packaging is a method used to preserve food by removing air from the packaging before sealing. This process inhibits the growth of bacteria and mold, extending the shelf life of the food product. Typically made from durable plastic films and materials, vacuum packaging is designed to create an airtight seal that protects food from external contaminants and moisture.
| Material | Plastic films, nylon, polyethylene |
| Seal type | Heat seal or pressure seal |
| Thickness | 50 to 200 microns |
| Barrier properties | Oxygen and moisture barrier |
| Temperature resistance | Up to 90┬░C for cooking |
When choosing vacuum packaging, consider the type of food being packaged and the desired shelf life. Specify the material based on barrier properties needed for your product, as well as the thickness for durability. It's also important to consider the sealing method, whether heat or pressure seal, depending on your machinery. Request information on any relevant certifications for food safety and hygiene standards.
