Food packaging plastic roll filmrefers to continuous, flexible plastic sheets supplied in roll form, specifically engineered for food contact and preservation. It serves as a critical barrier in the food industry, with three core functions: protecting food from external contaminants (moisture, oxygen, dust), extending shelf life, and enabling efficient, automated packaging. Its flexibility and customizability make it a cost-effective choice for small-scale producers and large manufacturers alike.
Different food packaging needs demand specific film properties. The table below outlines the most widely used types and their applications:
| Film Type | Base Material | Key Traits | Ideal Food Applications |
| Low-Density PE (LDPE) | Polyethylene | Flexible, moisture-resistant, heat-sealable | Fresh produce, bread, snacks |
| Biaxially Oriented PP (BOPP) | Polypropylene | High transparency, oil-resistant, stiff | Candies, biscuits, dried fruits |
| Polyester (PET) | Polyethylene Terephthalate | Strong oxygen barrier, durable, puncture-resistant | Frozen food, meat, seafood |
| Aluminum Foil-Laminated Film | PET/PP + Aluminum Foil | Superior light/oxygen barrier, heat-resistant | Retort food, vacuum-packed meat |
Food Processing Plants
Automated packaging lines rely on plastic roll film for high-speed operations—such as form-fill-seal (FFS) machines for snacks or frozen meals. Laminated films are preferred here for their durability and barrier performance.
Retail and Supermarkets
Fresh food sections use breathable LDPE roll film to maintain the crispness of fruits and vegetables, while packaged confectionery and baked goods often adopt transparent BOPP film to showcase products.
Small-Batch Production
Artisanal food makers (e.g., homemade jams, local snacks) use customizable roll film with printed logos, leveraging its low cost and ease of use for small-scale packaging.
As sustainability gains traction, recyclable and biodegradable food packaging plastic roll film (e.g., PLA-based or recycled PE/PP) is increasingly adopted. These films retain core protective functions while reducing environmental impact, aligning with global packaging waste reduction goals.
