3. Printing color: according to customer requirements
Most yogurt cup lid films use aluminum foil composite films, mainly to ensure high barrier properties of the seal and not easy to puncture. Yogurt packaging often uses a film made of aluminum foil as the cup lid film, which is a composite film formed by aluminum foil and other plastic films. Since yogurt contains a large amount of fat and protein components, its packaging materials are required to have high oxygen barrier properties, and the covering film of the aluminum foil composite material has high barrier properties, which can ensure the excellent oxygen barrier properties of the yogurt cup.
The yogurt cover film is mainly made of composite materials, with a structure of polyester/aluminum foil/heat sealing layer (PET/AL/PE-EVA).
The air tightness of aluminum foil is better than that of pure plastic. When observed under a magnifying glass, the plastic material actually has many small holes through which air and water can pass. Secondly, the aluminum foil composite film has high strength. The third is the sealing process. Yogurt is generally heat sealed.
- 1. Aluminum foil capping foil, also known as heat-sealing aluminum foil, is suitable for packaging yogurt, margarine, jam, honey and other foods.
- 2. Aluminum heat sealable foils should be further processed, painted or laminated using the different inks available on the market today and can be sealed to a variety of substrates such as PVC, PS, PP, PE and PET.
Aluminum yogurt lids are aluminum foil and plastic film compounded, or coated with glue, to become a good sealing material, used to seal plastic cups such as PP, PS, PET, or paper cups laminated with plastic films.
