Release liner

What is a Release Liner?

A release liner is a paper or plastic-based film sheet used in packaging. It acts as a protective layer that covers an adhesive surface until it is ready to be used. Think of it as the backing paper you peel off a sticker.

Why is a Release Liner Important?

The release liner keeps the adhesive surface clean and intact. This ensures that the adhesive remains effective when applied. Without it, the adhesive could get dirty or lose its stickiness.

Materials Used in Release Liners

Release liners can be made from various materials. Common options include paper, plastic films, and even silicone-coated materials. The choice of material depends on the specific needs of the packaging.

Applications of Release Liners

Release liners are used in many industries. They are essential in labels, tapes, and medical products like bandages. They also play a role in construction materials and automotive parts.

Environmental Considerations

Many companies are looking for eco-friendly release liners. Recyclable and biodegradable options are becoming more popular. This helps reduce waste and supports sustainable packaging practices.
