Large Rolls Of Aluminum Foil 9 Micorn 8011
8011 aluminum foil is not only hygienic, but also has good freshness and ability to keep moisture from losing. In particular, aluminum foil also has the characteristics of high thermal conductivity, sanitation, and impermeability, so it is widely used in cooking, freezing, baking, and preservation in hotels, restaurants and home kitchens. Specially processed 8011 barbecue aluminum foil products are more This industry is the icing on the cake.
How to choose composite materials reasonably is a key step in packaging. At present, the cooking temperature in the market is above 121℃ (inclusive), and the high-temperature cooking packaging containing aluminum foil mainly has the following two material structures, namely BOPET/AL/RCPP and BOPET/AL/BOPA/RCPP. In the following, the author will focus on analyzing these two structures, and discuss with you together, hoping to attract others and help you to make this kind of packaging well. BOPET is a kind of high-grade plastic film with excellent performance after biaxially stretched mainly using polyester (PET) chips as raw material. It has high transparency, non-toxic and odorless, high tensile strength and good stiffness. , Tearing resistance, not easy to break, excellent electrical and optical performance, oxygen barrier, good moisture barrier, cold resistance (-70℃), heat resistance (200℃), and excellent characteristics of chemical resistance and stable shrinkage. When choosing BOPET, attention should be paid to the thermal shrinkage rate of ≤2% in the longitudinal direction and ≤1.5% in the transverse direction under the conditions of 150℃ and 30min, and the surface tension should not be less than 45mN/m. Aluminum foil is the only metal foil in flexible packaging materials and has a long application time in the packaging field. Aluminum foil is a metal material, and its water-blocking, gas-blocking, light-shielding, and taste-preserving properties are difficult to achieve by any other packaging material, and it is a packaging material that cannot be completely replaced so far. Aluminum foil is made of electrolytic aluminum with a purity of 99.0% to 99.97%, which is produced after many times of rolling. It is rich in resources and has considerable advantages in cost performance. The aluminum foil for retort packaging should be 9 microns thick A grade soft aluminum foil.
Aluminium Foil Roll 1235 O For Flexible Packaging Dry compounding is suitable for the compounding of various composite film substrates and films
