Cold Forming Foil is the packaging material with highest barrier performance, which can absolutely resist moisture, oxygen and light. But it need drawing during packaging process, so sometimes there are bubble crack and delamination during drawing process. It leads to low efficient and high waste. The most serious is that it will bring hidden quality issue of medicine.
The structure of the existing cold pressed Blister aluminum foil for aluminum lamination is a three-layer composite shape, the core layer is aluminum foil, PVC layer is compounded on one side of the aluminum foil, and nylon layer is compounded on the other side. Even if the raw material aluminum foil and composite glue produced are imported from abroad, the laminated aluminum foil will often appear due to this structure. Because the composite is not solid, the laminated materials are easy to crack during cold punching and pressing, and the genuine product rate of production is low, resulting in the high production cost.
Because 8011-h18 foil is usually attached to the back of plastic packaging materials for sealing. Aluminum foil after compounding, printing and gluing is widely used as packaging material. Yutwin proposed a processing technology of cold formed aluminum foil that is not easy to be layered when heated.
Many factors including the packaging machine performance and mould design can take affect to the drawing result. We are always study how to make the cold forming foil can suitable for all kinds of machine and mould to avoid quality issue caused by above factors.
Its our always goal to improve the tensile property, in order to meet specific production requirements, Yutwin can supply material with different thickness. In order to satisfy your market needs, we can supply you various solution such as printing, contact us for more deatails WhatsApp +86 1800 1668 319.
