The diversity of packaging materials is the basis for meeting the needs of industries such as daily chemical, toys and beverages. Heat-shrinkable film labels and composite bags have their own advantag

Composite bags play a key role in food packaging, especially for perishable products such as tea and nuts. Pure aluminum bags and aluminum bags because of its excellent sealing, effectively block air and moisture, extend the shelf life of food. The design of eight-side seal and three-side seal further enhances the practicability and meets the needs of different scenes. Hongyu packaging and other enterprises through the integrated production process, from design to quality inspection to strictly control the quality, to ensure the safety and reliability of composite bags. For example, the use of high-speed printing presses and slitting machines improves precision and reduces material waste. This whole chain management embodies the concept of "fine service", that is, to improve customer experience through detail optimization. With the food line

As an important element of modern packaging, heat-shrinkable film labels are widely used in the daily chemical, food and wine industries. PVC, PET and OPS are common materials with their own characteristics: PVC has low cost but weak environmental protection, PET has high transparency and durability, and OPS stands out with high shrinkage rate and environmental protection advantages. With the increasing awareness of environmental protection, OPS has gradually become the preferred alternative to traditional materials. Its application not only improves the appearance of products, but also reduces the impact on the environment. Hongyu packaging and other enterprises through technological innovation, to promote the development of heat shrinkable film label to a more sustainable direction. For example, the use of non-dissolving machine composite technology, both to ensure production efficiency, but also reduce.

The compound bag is suitable for vacuum packaging or general packaging of food, electronic products, chemical industry, medicine, tea, precision instruments and national defense cutting-edge products. Raw materials: OPP, PE, POF, PPE, PP, composite film, etc. The process is divided into: side seal bag, bottom seal bag, middle seal bag and three side seal. Four different machines are required. Material classification 1. Material: BOPP/LLDPE two-layer composite characteristics: moisture-proof, cold-resistant, low-temperature heat sealing and strong tensile strength; Uses: instant noodles, snacks, frozen snacks, powder packaging, etc. 2. Material: BOPP/CPP two-layer composite characteristics: moisture-proof, oil-resistant, high transparency and good stability;

POF is a kind of heat shrinkable film, which is mainly used for packaging regular and irregular shaped products. Due to its non-toxic and environmental protection, high transparency, high shrinkage rate, good heat sealing performance, high gloss, strong toughness, tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging, POF is a replacement product of traditional PVC heat shrinkable film, widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3,VCD, handicrafts, photo frames and other wood products, toys, pesticides, daily necessities, food, cosmetics, canned drinks, dairy products, medicine, cassettes and video tapes and other products. Main features 1, high transparency

OPS (oriented polystyrene) heat shrinkable film is a new type of packaging material that meets the requirements of environmental protection. OPS heat shrinkable film has high strength, high rigidity, stable shape, and has good gloss and transparency. Convenient processing, easy coloring, good printing performance, and extremely high printing resolution. For the trademark that continues to pursue exquisite printing, it is completely a material progress. Due to the high shrinkage and strength of OPS film, it can be closely fitted with containers of various shapes, so it can not only print out exquisite patterns, but also meet the use of novel packaging containers with different shapes. This kind of non-toxic

PET printing, refers to the polyester film, that is, polyethylene terephthalate film printing engineering. Polyester film overview Polyester film, that is, polyethylene terephthalate film, is a film made of high-quality polyester chips as the main raw material, using advanced process formulas, after drying, melting, extrusion, casting and stretching. Since 1948 the British Imperial Chemical Company (I .C. I) and the United States DuPont Company (DUPONT) developed polyester film, and in 1953 to achieve the industrial production of biaxially oriented polyester film, polyester film in many fields have a wide range of applications. different uses
