Transparent food cans and containers are one of the most popular packaging formats today, allowing the contents to be clearly visible at a glance. To help its customers successfully catch consumers' attention in a demanding market environment, Innovia Films has developed a new fully transparent label film. Innovia says this exceptionally transparent film is unprecedented in the industry and presents brands and their products more visually. The film has been named Ra

Hunan Shangpin Packaging: Regular pouch: PET (printed) laminated to BOPA and then to CPP (three-layer pouch). After being made into finished pouches, the PET peels off entirely with a gentle pull, and there is not a trace of ink on the laminated BOPA layer. What is going on? Lin Xiwen, Yawei Color Printing: What ink was used? Hunan Shangpin Packaging: Retort ink was used. Wang, Xin'an Packaging: 1. No adhesive applied or adhesive coating weight too low; 2. Abnormal adhesive quality; 3. Almost no pressure from the lamination rollers during the two-layer lamination

Solvent-free adhesives are a technology developed in the 1970s. Using solvent-free adhesives to laminate films can reduce energy consumption, improve production efficiency, enhance product quality and lower overall production costs. Because they contain no solvents, they are conducive to environmental protection and clean production, and are therefore attracting increasing attention from professionals in the flexible packaging industry. However, there are also many challenges to be solved in their use. Challenge One: Significant Impact on the Slip Properties of PE Films In the solvent-free lamination process

1) Start-up Conditions Start-up work may begin only after the start-up preparation work has been completed. 2) Start-up The machine operator starts the main motor to make the plate cylinder run at low speed, and at the same time starts the burner, oven temperature and fans. 4) Taping The ink mixer and the unwinding/winding workers wrap the plate cylinder end caps and the threaded parts of the plate shaft with adhesive tape, so as to prevent ink from adhering to them during operation and affecting the next plate mounting. 5) Raising the Ink Trough The three people act separately: raise the ink trough so that the plate

PE film blown with SF solvent-free dedicated anti-block and slip masterbatch is suitable for curing solvent-free laminated products at relatively high temperatures (e.g., 40°C), effectively solving the industry-wide phenomenon of increased coefficient of friction in PE solvent-free lamination. The test data are as follows: [Multiple solvent-free adhesives in the industry were used for testing at different coating weights under relatively high curing conditions, and relatively ideal COF results were obtained in all cases, sufficient to cover different application conditions, demonstrating the technical versatility of the solution.

An inconspicuous packaging bag on the market has its own story behind its production, and the production of packaging bags and packaging technology are among them. Today we explain the requirements that food packaging bags place on packaging technology. I. The protective requirements of food must be understood Different foods have different chemical compositions and physicochemical properties, so different foods have different protective requirements for food packaging bags. For example, cake is oily, soft, and has a certain optimal moisture content requirement, so at a minimum it should meet the following requirements...

Some resins or film products have inherent properties that do not suit the requirements of the processing technology they require, so additives need to be added to change their processability; other materials have good processing performance, but their product performance cannot meet requirements, so additives also need to be added to change their product performance. Requirements of Film for Additives Poor compatibility will trigger a "migration" phenomenon, manifested as "sweating" in liquid additives and "blooming" in solid additives. Sometimes when the requirements for the film are not particularly strict

As is well known, gel particles are a common problem for film manufacturers. For transparent plastic bags, gel particles noticeably affect their appearance. For plastic bags that require higher printing quality, especially large-area plastic bag printing, the "white spot" rejects caused by gel particles account for a relatively large proportion of losses in the plastic bag industry's production process. Therefore, controlling the formation of gel particles and eliminating their causes are important process steps in improving the technical level of the plastic bag industry. 1. What are gel particles

Vacuum packaging technology, MAP packaging technology and deoxygenation packaging technology have increasingly catered to the major trend of market development. Food manufacturers not only make great efforts in the healthiness, nutrition and flavor of their products, but also keep innovating food packaging, in addition to more exquisite and more distinctive appearance designs. But did you know that differences in packaging materials and methods, especially barrier performance, will directly affect the shelf life of your products. From the perspective of food safety, packaging

Under the action of a certain temperature and pressure over a period of time, adjacent layers of plastic film may sometimes adhere to each other; if high winding resistance is observed, it indicates that the roll film has blocked. When the curing temperature in the curing room is too high, the roll film is also prone to blocking and must be rewound before normal use. These phenomena indicate that packaging materials have tackiness; in fact, this tackiness is caused by the thermal motion of chain segments. Causes of Plastic Film Tackiness If the ambient temperature is above the T
