Abstract

The invention discloses a puncture-resistant BOPET film for aluminizing and a preparation method thereof. The film is composed of an upper surface layer, a core layer and a lower surface layer. The core layer is prepared from the following raw materials by mass percent: 60%-80% of PET polyester chips and 20%-40% of ENBA copolymerization modified PET polyester chips, wherein the upper surface layeris prepared from the following raw materials: 5% to 10% of PET polyester chips, 10% to 20% of ENBA copolymerized modified PET polyester chips, and 70% to 85% of PET polyester anti-stick master batch.The lower surface layer is prepared from the following raw materials: 30 to 35 percent of PET polyester chips and 65 to 70 percent of PET polyester anti-sticking master batch. The BOPET film has excellent strength, breaking nominal strain, puncture resistance and the like, and a produced product has more advantages in the aspects of performance, production cost, environmental protection, energy consumption and the like.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a puncture-resistant BOPET film for aluminum plating and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy, the requirements for packaging of commodities have become higher and higher. Many irregularly shaped and angular commodities, such as foods containing sharp objects such as bones and fishbone, etc., are often damaged at the corners of the ordinary aluminized composite film due to the stretching of the aluminized layer during the vacuum packaging process, thus Affect the effect of product packaging. This requires that the aluminized film has good puncture resistance. [0003] For heavy-duty packaging composite films, in addition to the conventional physical properties such as composite strength and tensile strength, puncture resistance is also an important indicator. In practical applications, ...
