The composition of the inner layer of the tea packaging bag

The composition of the inner layer of the tea packaging bag According to the introduction of the tea packaging bag manufacturer YLTpacking packaging bags, most of the tea packaging bags on the market are made of aluminum foil bags, of course, there are also a small part of kraft paper. Aluminum foil tea packaging bag is the best packaging bag to protect tea. The quality of the composite aluminum foil bag is better, especially the product made of nylon with good printing performance, and the quality is more concerned by consumers. What is the composition of the inner material of the tea packaging bag? The inner layer of tea packaging bags is usually made of pure aluminum foil. Aluminum foil is the best material to protect tea leaves, followed by aluminum-plated bags. Aluminum-plating is not as good as aluminum foil. The greater the thickness, the better the protection performance of the tea leaves. The main tea bags in YLTpacking packaging are as follows: 1. Plastic composite tea packaging bags Plastic composite bags have many advantages such as light weight, not easy to break, good heat sealability and reasonable price, and are widely used in packaging. There are many kinds of composite bags used for tea packaging, and the composite film has excellent gas barrier properties, moisture resistance, aroma retention, and anti-peculiar smell. Since most plastic films have a light transmittance of 80% to 90%, in order to reduce the transmittance, UV suppression can be added to the packaging material or the light transmittance can be reduced by printing and coloring. In addition, a composite material based on aluminum foil or vacuum aluminized film can be used for light-shielding packaging. There are various packaging forms of composite film bags, including three-sided sealing, stand-up bag, and folding. Since the composite film bag has good printability, using it for sales packaging design has a unique effect on attracting customers and promoting tea sales. 2. Vacuum tea packaging bags Vacuum bags, also known as personal moisture-proof bags, aluminum foil bags, and aluminum-plastic composite bags, are generally made of NY/PE or PET/NY/AL/CPE. Among them, PET—good printing effect, NY (nylon) – Low oxygen permeability, high strength, AL (aluminum foil) – opaque, CPE – inner layer of packaging, excellent heat sealing performance. Among these raw materials, nylon is usually a necessary raw material for making vacuum bags. Glue for vacuum bags: water-soluble glue (more hygienic, environmentally friendly, and free of solvent residues) This product has good anti-static, oxygen barrier, shielding, moisture-proof, shading functions and excellent heat-sealing properties. According to the special requirements of users in various industries, this product can add anti-static function, print product descriptions, company trademarks, and anti-static signs without changing product performance. It is suitable for products that need vacuum bag packaging, electronics, communications, national defense and military industries. 3.
