Product Specifications
Heat seal lidding film is available in multiple gauges and widths, tailored to meet specific packaging equipment and product requirements. Typical thickness ranges from 25 to 100 microns, providing flexibility between lightweight economy films and heavy-duty barrier solutions. It can be supplied in roll form for high-speed sealing applications or pre-cut sheets for specialized packaging formats. Surface finish options include glossy, matte, or metallized layers, each designed to enhance brand visibility and consumer appeal. films can be engineered with high-barrier layers such as EVOH or aluminum coatings, depending on the level of protection required. All materials comply with international food safety standards, ensuring both performance and regulatory peace of mind.
Product Instructions
To achieve optimal sealing performance, it is recommended that the heat seal lidding film be used with compatible sealing equipment and container substrates. The sealing temperature range typically falls between 160°C and 220°C, depending on the specific film structure and packaging application. For peelable films, uniform pressure should be applied during sealing to ensure consistent opening performance without tearing. The film should be stored in a cool, dry environment away from direct sunlight to preserve its sealing and barrier properties. Prior to large-scale production, we recommend conducting a trial run to calibrate equipment settings and confirm film compatibility with the intended product and container type.
