To respond directly to shifting consumer trends, Mondi will showcase its latest range of products at Interpack 2017. The products on display will highlight ease of use and sustainability. For example, at one corner of the cornerpack pouch, Mondi has added a semicircular tear line, making it easier for consumers to tear open the packaging and pour out the contents. At the same time, to help consumers enjoy the taste and aroma of products for longer,

A flexible packaging plant: We are printing a large-area spot color on a surface-printed product and keep getting small tailing streaks, at both high and low viscosity. After scratching with a chopstick, they reappear after a while. Is it due to slow machine speed, coarse ink particles, or other reasons? Pearlized OPP, surface printing ink. Shenzhen – Packaging Bags: Try filtering the ink. Yinteng Packaging Yu Dingzhao: The ink probably has impurities. Try filtering it. Shangyang Packaging - Qi: Try adding a little water to the ink. Yinteng Packaging Yu Dingzhao: Adding water is

Although in theory solvent-free lamination can produce any product structure that dry lamination can, in practical applications many structures that are dry laminated smoothly show abnormalities when they are solvent-free laminated, especially high-temperature (above 121℃) retort products. For example, structures laminated with aluminum foil and high-temperature retort products with three or more layers often encounter various problems. Among the high-temperature retort product structures commonly found on the market today, such as BOPET//RCPP

Translated by Deng Wentao, Packaging Frontier Barton Group has expanded the application range of its patented dispensing pouch technology, SqueezyStraw. Headquartered in New York, the company partnered with Multivac to launch the stand-up pouch, initially trialed in an 8-ounce clear milk package. The package features a squeeze function that makes it easy to squeeze out the milk. Beyond milk, Barton Group President Lew Barton said the patented technology can also

Generally, the friction coefficient μs of the treated surface of BOPA film is between 0. 4~0. 7. The friction coefficient of BOPA film is divided into kinetic friction coefficient and static friction coefficient. In the production process of BOPA film, the friction coefficient of plastic film is an important technical indicator. On the one hand, together with the anti-blocking performance of the film, it serves as a quantitative evaluation index of the openness of plastic film; on the other hand, it can also serve as reference data for the running speed of automatic packaging machines, tension adjustment, and during film running

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.
