PET self-adhesive is a self-adhesive material based on polyethylene terephthalate (PET). It is usually coated with pressure-sensitive adhesive (such as acrylic glue, rubber-based glue, etc.) on the surface of PET film and then combined with release paper (silicone oil paper) to be made. Its structure generally includes PET substrate, adhesive layer and release layer, and belongs to high-molecular material label consumables.
Characteristics of PET self-adhesive
1. Outstanding physical properties
High strength and tensile resistance: The PET material itself is strong and has good toughness, and is not prone to tearing or deformation, suitable for scenarios requiring resistance to external forces (such as packaging labels, industrial signs).
High temperature resistance and low temperature resistance: It can maintain stability within the temperature range of -40℃ to 120℃. Some specially treated PET self-adhesive can withstand temperatures above 150℃, suitable for use in high-temperature environments such as electrical appliances and automotive components.
Chemical resistance: It has good resistance to acids, alkalis, and oils, and is not easily dissolved or deteriorated by contact with solvents, often used for cosmetics and pharmaceutical labels.
2. Optical and appearance characteristics
High transparency: Transparent PET self-adhesive has high light transmittance, can present clear printing effects, and can also be used for semi-transparent or matte texture label designs.
Surface smoothness: The substrate surface is smooth, suitable for high-precision printing (such as color graphics, barcodes, QR codes), with good ink adhesion, and patterns are not prone to fading.
3. Stable adhesive performance
Long-lasting adhesion: Acrylic-based adhesives have good adhesion on various surfaces (such as metal, plastic, glass), and are not prone to detachment over time, suitable for outdoor or durable labels.
High weather resistance: Resistant to ultraviolet rays, moisture, and oxidation, not prone to aging in humid and direct sunlight environments, suitable for outdoor product labels, food packaging labels.
4. Environmental friendliness and processing adaptability
Recyclability: PET is a recyclable plastic (recycling symbol #1), in line with environmental protection requirements, but note that the adhesive layer may affect the purity of recycling.
Easy processing: Can be personalized processed through die-cutting, hot stamping, laminating, etc., to meet different shapes (such as round, irregular shapes) and decoration requirements.
