In daily life, we often encounter Lamination Film and heat shrink film. Although they are all made of plastic, there are significant differences in characteristics and usage scenarios.
1. Raw materials and manufacturing
Lamination Film is usually made of polyethylene (PE) material, while heat shrink film is made of multi-layer composite materials, including polyethylene, polypropylene (PP), polyvinyl vinyl ester (EVA), polyester ( PET), etc., and sometimes additives such as antistatic agents and anti-UV agents are added.
2. Comparison of features
Lamination Film
Softness and transparency: Lamination Film is usually soft, has high transparency, and has rich colors.
Wear resistance: It has good wear resistance and is not easy to fade, yellow, deform or deteriorate after long-term use.
Smooth surface: Its surface is very smooth and is very suitable for painting on it with colored pens, watercolor pens, markers and some pigments, so it is often used as a painting material.
Heat shrink film
Shrinkage: The heat shrinkable film will automatically shrink after heating, tightly covering the product, and has strong shrinkage and anti-permeability.
Thin and hard: Heat shrinkable film is relatively thinner, harder, and more transparent, but the material is brittle and not suitable as a painting material.
Mechanical properties: Heat shrink film has high mechanical properties and heat resistance, and is suitable for automated packaging.
3. Other matters needing attention
·Use of Lamination Film: Lamination Film needs to be heated with a laminating machine. Different thicknesses require different laminating temperatures, as well as appropriate pressure and speed.
·Heating of heat shrinkable film: The heat shrinkable film will automatically shrink during the heating process. This process requires controlling the heating temperature and time to ensure the packaging effect.
