Solvent-free Recombination in Flexible Packaging
No solvent recombination in flexible packaging refers to the manufacturing process that avoids the use of solvents during the production of flexible packaging materials. This approach is increasingly important for environmental sustainability and safety in packaging applications.
Boiling disinfection method is a common sterilization method for food packaging, which is generally boiled at 100 ℃ for 30 minutes to kill the reproductive body of bacteria, and has a better disinfection effect. However, the boiling link also poses a challenge to the composite effect of the packaging bag.
The solvent-free composite plays a very important role as the "core member" of the packaging:
1.The product has good matching with ink, and high adaptability with various film materials, and can cover a variety of composite structures; The composite effect has high transparency, providing strong support for the decorative and aesthetic requirements of the packaging bag.
2.No odor, to meet the needs of high odor sensitivity application scenarios, such as cat and dog food and pet food packaging and pharmaceutical industry product packaging.
3.The opening period of the tank is long, and the product viscosity is still lower than 3500 mPa ·s at 60min. After curing speed is fast, to solve the problem of slow curing in winter; It can achieve normal temperature coating and rapid curing at room temperature, significantly reduce energy consumption, and help customers achieve cost reduction and efficiency improvement.
4.Aluminized structure has high composite strength and excellent packaging barrier performance.
