Presstopack (press-to-pack) provided by GRETO, utilizes revolutionary cold seal technology and is a modern packaging solution with applications across a wide range of end packaging usages. Presstopack can be easily cut to size to suit each item being wrapped, in turn eliminating waste from leftover pieces. This product is supplied on rolls of up to 1 meter width.

The fluted layer of Presstopack uses a special type of pressure sensitive adhesive that forms a strong bond at room temperature with the application of very slight pressure. Importantly, this cold seal technology only bonds to itself and will not stick to any other surface, making it easy to store and handle.
