Transferable laser aluminized base film usually refers to laser transfer aluminized film, which is a kind of various packaging decoration materials produced by laser holographic technology, suitable for the printing and packaging industry.
Definition and classification
Definition: Laser transfer aluminized film is to transfer the local aluminized laser positioning to the required part of the surface printing film. The transferred graphics can be text, graphics or lines.
Classification: According to different raw materials, laser aluminized film can be divided into BOPP aluminized film, CPP aluminized film and PET aluminized film.
Characteristics and application
BOPP aluminized film
Characteristics: It is made of BOPP film as raw material and processed by vacuum aluminization. The aluminized layer is plump and smooth, the aluminum layer has good adhesion, and has strong adhesion to ink.
Application: It is widely used in soft packaging, handbags, wrapping paper, gift boxes, composite, decoration, laser holographic anti-counterfeiting, laser embossing laser and other fields.
CPP aluminized film
Features: Made of CPP film as raw material, it is processed by vacuum aluminizing. It has the characteristics of low initial sealing temperature, wide heat sealing temperature, high strength, high gloss, strong metallic feel, and good aluminizing uniformity.
Application: Widely used in soft packaging composite, food packaging, toys, balloons and other fields.
PET aluminized film
Features: Made of PET film as raw material, it is processed by vacuum aluminizing. The aluminum layer has good adhesion and strong adhesion to ink. It is suitable for various printings such as lithography, gravure and flexography.
Application: Widely used in printing, composite, lace, textile gold and silver thread, self-adhesive and other fields.
Production process and technology
The production process of laser transfer aluminized film usually includes film preparation, vacuum aluminizing, laser holographic pattern production and transfer and other steps. Among them, laser holographic technology is the key technology for making laser patterns. It uses the interference and diffraction principles of lasers to record specific patterns or text information on the film to form a laser pattern with a unique bright and dazzling color-changing effect.
