Lithco Shrink Film

Centerfold film is folded in half on the roll, so the open width is wider than the folded width. The product goes between the layers, then the open sides are sealed before heat is applied. Buyers should choose a roll wide enough to cover the product’s width, height, and side allowance. A common mistake is measuring only the flat face of the product and forgetting thickness. That can make the seal too tight or prevent the edges from closing. When in doubt, size the film around the full product shape, not only the front dimensions.

Yes, the product context supports use with heat sealing equipment, heat guns, and shrink tunnels, depending on the specific film option and workflow. A heat gun may suit smaller batches, repair work, or low-volume packaging. A shrink tunnel is better for repeated production because it applies heat more evenly and quickly. The right setup depends on volume, package size, and finish expectations. If you are building a wider packaging workflow, shrink wrap equipment may help match film with sealers, tunnels, or heat tools.

Choose 500' rolls for lower-volume use, testing, or jobs where you need several widths without overstocking. Choose 2000' rolls when the same package size runs often and the film width is already proven. Longer rolls reduce roll changes and can support more efficient production, but they only help if the width and gauge match your normal jobs. For a new product, test sizing before committing to a longer roll. Also consider storage space, machine setup, and how often operators switch between product sizes during the day.

The wrong size can cause weak seals, excess film, torn corners, poor shrink, or packages that look loose. If the roll is too narrow, the film may not close around the product. If it is too wide, extra film can bunch at the edges and reduce the finished look. Gauge also matters because the film must protect the item without being harder than needed to shrink and seal. For higher-volume packaging lines, shrink tunnels can support more even heat and a cleaner finish than hand shrinking alone.
