Polyurethane adhesives can be regarded as the "bonding master" in modern industry, especially in the field of flexible packaging. With its unique and comprehensive excellent performance, it has become the top choice for producing high-performance and high-appearation-level packaging materials.
Outstanding performance and core advantages in flexible packaging:
1. The broad-spectrum adhesion that can bond everything: This is the most prominent advantage of polyurethane adhesives. Whether it is common plastic films (such as PET, BOPP, NY, PE, CPP), or difficult-to-bond aluminum foil and aluminum-coated films, it can form an extremely strong bond. Its outstanding wettability and chemical bonding capacity can effectively overcome the problem of large differences in surface tension among different materials, achieving a perfect composite of "heterogeneous materials", and completely solving the problems such as delamination and white spots that are prone to occur when traditional adhesives are used to composite aluminum foil or aluminum-coated film.
2. The comprehensive performance of toughness and durability: The composite packaging bags made of it have performance far exceeding that of ordinary products.
3. Excellent weather resistance: It can withstand high and low temperature changes (such as cooking and freezing), ensuring no delamination or cracking in harsh environments.
4. Chemical resistance: It can resist the erosion of packaging contents (such as oil, acid, spicy, flavorings, solvents), prevent ink leakage and odor migration, and maintain the flavor and safety of the contents for a long time.
5. Strong flexibility: The cured adhesive film is soft and elastic, perfectly matching the flexibility of the packaging bag. It can remain intact even when repeatedly squeezed or dropped, eliminating the risk of package breakage.
6. High transparency and high aesthetic appeal: Polyurethane adhesives themselves have a light color and high transparency, which will not cover the bright colors of the ink. They can fully display the exquisite details of the packaging design, making the goods on the shelves more eye-catching and directly enhancing the product grade and consumers' purchasing desire.
7. Good adaptability to production processes: It is suitable for various mainstream production processes such as dry lamination and solvent-free lamination. With a wide operation window, it is easy to process and can effectively help production enterprises improve efficiency and yield.
Choosing polyurethane adhesives means you are choosing more secure packaging, longer-lasting preservation, superior barrier properties and a more attractive appearance. It is not only the glue that bonds multiple layers of films together, but also a powerful guarantee for enhancing the overall value of your products and winning market competitiveness. Investing in top-notch bonding solutions is investing in your brand's reputation and future.
