Concept of Cosmetic Thermal Transfer Film

1. Concept of Cosmetic Thermal Transfer Film
Cosmetic thermal transfer film is a decorative film applied to cosmetics. It is mainly designed, laid out, and transferred on the surface of cosmetics such as powder boxes, moisturizing cream jars, lipstick shells, eyebrow pencil packaging, mascara shells, blush bottles, moisturizing water bottles, etc. It is very common in daily life.

2. Material of Cosmetic Thermal Transfer Film
Cosmetic thermal transfer film uses a transparent film as the base film, and its material can generally be divided into three types:

A. OPP: large elasticity, large punching pressure, but poor high temperature resistance.

B. PET: small elasticity, good stability, the most widely used of the three, accounting for about 80% of the product base film.

C. PVC: The material is extremely versatile, corrosion-resistant, good insulation, and has a small molding temperature range.

3. Hot stamping temperature of cosmetic thermal transfer film
During the processing of cosmetic thermal transfer film, since cosmetics are composed of a variety of materials, different hot stamping temperatures need to be adjusted for different product materials.

For example, the hot stamping temperature of PE material is 220℃-260℃;

The hot stamping temperature of EVA and PVC materials is 140°C-160°C;

The hot stamping temperature of ABS material is 180°C-200℃;

The hot stamping temperature of PC material is 160℃-200℃;

The hot stamping temperature of the cosmetic surface of metal material is about 220℃-270℃;

The surface strength of PP is relatively high, so when we make the transfer printing film, we need to adjust the pressure and temperature higher, and the temperature is generally controlled at 240℃-260℃

4 Design principle of cosmetic thermal transfer film
Its design principle is to design the artwork and layout according to the unfolded area after the shape of the cosmetics (powder box, moisturizing cream jar, lipstick shell, eyebrow pencil outer packaging, mascara shell, blush bottle, moisturizing water bottle) is unfolded.

When calculating the unfolded area, the "shrinkage" of the cosmetic product and the "stretching" of the thermal transfer film should also be estimated. This way, the actual printing area of the cosmetics can be accurately calculated, thereby designing accurate thermal transfer graphics.
