G-PET film for sealing against blister cards refers to a specific type of glycol-modified polyethylene terephthalate (G-PET) film used in packaging applications to seal against blister cards. Blister cards are packaging materials commonly used in the pharmaceutical, medical, and retail industries. They consist of a plastic cavity (blister) that holds the product (such as tablets or capsules) and a backing card usually made of paperboard or another type of rigid material. G-PET films used for sealing against blister cards are designed to provide a secure and tamper-evident seal, protecting the enclosed products from moisture, contaminants, and physical damage. These films are chosen for their excellent clarity, mechanical strength, and ease of processing. They are often used in combination with heat-sealing equipment to create a tight seal between the blister card and the film, ensuring product integrity and preventing tampering. The sealing process typically involves applying heat and pressure to the G-PET film, causing it to adhere securely to the blister card, creating a protective barrier around the products inside the blister. G-PET films used for this purpose are engineered to have specific sealing properties, ensuring a reliable seal that meets industry standards for safety and quality.
