1. Material Targeted Composition: Printed composite bags are made up of various materials and can be tailored to the specific uses of the bags by adjusting the materials used. For example, for clothing and garments, a two-layer material of nylon composited with PE can be used; for metal parts, an additional layer of aluminum foil material may be added, and so on.
2. Production Process: Printed composite bags can be produced through processes such as gravure printing, dry lamination, and solventless lamination. The production techniques can be adjusted according to the specific uses of the bags, such as the ratio of adhesives and the method of lamination.
3. Environmental Friendliness: Compared to traditional plastic bags, printed composite bags are more environmentally friendly, with some products utilizing recyclable and biodegradable functional flexible packaging solutions.
4. Transparency and Printability: Although the PA/PE material itself may not have the high transparency of PET, the printability of the PA/PE material is good, allowing for various printing options to enhance the brand image of the product.
5. Diverse Material Structure: The structure of composite bags is typically divided into the outer layer, barrier layer, and inner layer, each serving different functions. The outer layer often uses materials with good transparency or opacity, featuring excellent printability and strong heat resistance. The middle barrier layer effectively prevents the permeation of gases or liquids from the inside and outside. The inner layer is non-toxic and made of materials that comply with international standards, exhibiting chemical inertness to avoid reactions with the packaged goods that could lead to corrosion or permeation.
6. Wide Application: They are widely used in various fields such as clothing and apparel packaging, industrial packaging, daily chemical packaging, food packaging, pharmaceuticals, health, electronics, aerospace, technology, military, and defense.
7. Printability: The surface of printed composite bags is smooth and flat, making them suitable for various custom patterns and text printing, which enhances product recognition and brand image.
