Common types of plastic tags and characteristics
And the substrate compared to paper tags, plastic tags substrate material has a high gloss, relatively smooth surface, excellent resistance to water (wet) and in the moist environment of excellent dimensional stability. Plastic tags substrate applications increasingly widespread in recent years.
Polyethylene film (PE)
PE film in its physical and mechanical performance and PVC film has some similarities, but also because of its excellent dimensional stability and is widely used in the packaging field. Corona treatment by general industry can reach the surface of PE film printability and coating of the can. According to need, corona effect lasts at least 6 months (corona level greater than 38mNm). PE film can be printed again before the corona treatment (corona refresh).
PE film thickness can be adjusted to its use in different application areas. Such as 150 micron film for chemical and industrial products; 80 to 100 micron film for shampoo bottles, cosmetic bottles and living supplies. PE film is a polyolefin polymer of carbon water, its chemical composition determine the environmental compatibility of PE film and a high degree of recyclability.
Polypropylene (PP)
One-way stretch and biaxially oriented polypropylene film can be cast to its excellent machining properties, good visual effects and a relatively thin surface film thickness together. And PE films compared to the disadvantage of PP film corona treatment effect is relatively short (in 38mNm corona level, usually in the corona 1-1 half months after the printing suitability).
And PE films like, PP film thickness can also be adjusted to apply it to different application areas. Such as 60 micron PP film can be used for hard, high transparent bottles: shampoo, cosmetics, food, cleaning fluids, etc.; 50 microns can be used for beverages, nutritional supplements, medicines and other "no label" a sense of the packaging vector; 30 to 40 micron PP film can be used for brochures and beverage labels, cosmetic and hygiene products such as "no label" a sense of the packaging vector.
PP film is also a polyolefin polymer of carbon water, its chemical composition determine the environmental compatibility of the PP film and a high degree of recyclability.
Polystyrene film (PS)
PS determines its chemical structure at room temperature with excellent cutting and excellent dimensional stability. But the anti-(block) oil (fat) is poor. PS is not a polyolefin. Its environmental compatibility and recyclability of relatively less than the polyolefin polymer.
Polyester film (PET)
Polyester film is a super transparent film with excellent dimensional stability. Its outstanding visual performance and relatively thin thickness so that a "sense of no label" label applications to make good choices.
12 micron PET film can be used for the surface of composite materials. High-quality look and feel with the protection of its material to be simultaneously in this embodiment. 50 micron PET film labels can be used for water, oil and chemical-sensitive packaging body.
While PET is not a polyolefin, but it can be washed and chopped for effective recycling and granulation made fibers, films and PET bottles.
Polyvinyl chloride film (PVC)
The main characteristics of PVC film color, thickness and hardness of diversity. PVC raw material does not contain heavy metals present, but still use softener. PVC determine the chemical structure of this material is suitable for outdoor use (2 to 7 years of outdoor use period). PVC film for containing chloride, its environmental compatibility and recyclability of the long-standing controversy.
In the plastic tab, polyethylene (PE) and polypropylene (PP) film processing because of its relatively wide temperature range (up to 260 ° C) and excellent mechanical and rheological properties has become the most widely used plastic label substrate .
