What is an easy-to-tear line?

Easy-tear line packaging originated in Europe in the 1990s. The reason was to reduce harm to children, solve the problem of plastic packaging, and promote child-friendly and harmless product packaging. Later, the easy-tear line was not only used for children's packaging, but also extended to medical products, food packaging, pet packaging, etc. Compared with traditional ordinary plastic packaging, the easy-tear line has outstanding opening performance advantages.

What are the characteristics of laser easy-tear line?

1. Easy to tear and open

Ordinary plastics are easy to seal, and peeling and opening require a lot of force, which can easily spill objects or liquids in the package, causing unnecessary waste. Children who are much smaller than adults find it difficult to open some packages by themselves, and need the help of their parents, which is inconvenient to use.

The tear strength of the tear film is low, and it is easy to tear vertically and horizontally after bag making. After using the easy tear line, it is easier for consumers to open the package without affecting the sealing of the package. During the opening and peeling process, the force is stable and stable, and it is easier to open. No objects or liquids are sprayed, which can provide consumers with better use performance, and the material is more suitable for children's packaging. When children open the package, they can provide better protection for children.

2. Cost saving

Tearing film only requires a lower sealing temperature, which is suitable for lower n-hexane precipitation in high-speed automatic packaging to meet the hygienic properties of medicines and reduce production costs.

Currently, easy-tear lines are mainly used for food and medicine packaging. Especially in marinated egg packaging, meat product packaging, snack food packaging, etc., it has been widely used.

3. Wide application

Due to the excellent sunshade, moisture-proof, airtightness and barrier properties of PE easy-tear line packaging, it can be widely used in various food, medicine, cosmetics and other packaging. This kind of PE easy-tear line packaging is usually composed of OPP matte, PET, pure aluminum and PE. Like the facial mask we often use, it is easy to tear the line.

In addition to daily necessities and pharmaceutical packaging, easy-tear lines are also widely used in agriculture, sheets, packaging bottles, electronic appliances, auto parts, mechanical equipment and other fields.
