What they are
These are pre-cut liners made from aluminum foil/plastic films, with a heat seal layer on the bottom. The heat seal layer is what bonds to your container rim when you apply heat and pressure.
What they do
They create a tight seal. No air leaks. No moisture gets in. Your product stays fresh and protected.
Where they work
These films stick to most rigid containers – plastic or metal. That means they work for:
- Food products (sauces, spices, dry goods)
- Cosmetic products (creams, masks, powders)
Any container with a flat rim that needs a reliable seal
Why choose custom shapes
Round is standard. But square, oval, or unique shapes help your brand stand out. We cut the film to match your container exactly. No trimming. No mess. Just place it on the rim and seal.
Simple. Reliable. Made for your container.
