n recent years, the traditional metal and glass containers in the daily chemical industry have been gradually replaced by lightweight plastic hose packaging. The reason is that plastic hose has the following advantages: the use of plastic hose is sanitary and convenient, the surface is bright and beautiful, so it has been widely used in paste cosmetics packaging, such as In cosmetics industry, the packaging of cleanser, hair conditioner, hair dye, toothpaste and other products, as well as the packaging of frost, paste and other external medicines in medicine industry. Plastic hose packaging is economical and convenient, easy to carry, even if the high-strength body extrusion, can still restore the original state, maintain a good appearance. Data show that 60% to 70% of hoses are used in cosmetics industry, 10% to 15% in medicine industry, and about 5% in food industry. Therefore, how to better realize the design concept of products through hose packaging, strengthen the decorative effect of hose packaging, and more quickly attract the eyes of consumers and match the brand temperament, has become an important topic for end users to think about. Plastic hose packaging product structure The main part of plastic hose includes shoulder, tube (tube body) and tail. The tube part is often decorated by direct printing or sticker label to carry text or pattern information and enhance the value of product packaging. Hose decoration is mainly achieved by direct printing and sticker labels. Direct printing, including screen printing and offset printing. Compared with direct printing, the advantages of self-adhesive labels include: printing diversity and stability: offset printing and screen printing are usually used in the traditional pre-made tube reprinting process of extrusion hose, while non-dry offset printing can adopt a variety of combination printing processes, such as relief, flexo, offset printing, screen printing and gilding, with high difficulty in color. Performance is more stable and excellent. Reducing Inventory Cost and Risk: Customer's demand for faster delivery time drives hose manufacturers to improve production efficiency. Direct printing requires inventory of hose products, which is more costly. The supply cycle of adhesive labels is shorter. Only bare tube inventory is needed to reduce the risk of outage. At the same time, the application of self-adhesive labels in hose packaging needs to meet the following conditions: the characteristics of high-strength peripheral extrusion of hose require excellent extrusion resistance of label materials; hose label materials constantly pursue uniqueness and good handle, and the label deformation after filling requires hose label materials. Better softness and stronger adhesives to ensure smooth and attractive appearance throughout the use process; widespread hose applications have raised concerns about label weatherability and content resistance; hoses and labels need to withstand the harsh challenges of practical application. For example, hose packaging for sunscreen products needs to pass the test of strict sunproof, high temperature and high humidity application.
