Dairy products have complex components and are easily affected by temperature, oxygen, light, microorganisms, mechanical effects, etc., which can lead to product discoloration, oxidation, damage, and deterioration, thereby shortening the shelf life. Therefore, packaging not only needs to have high barrier properties, but also needs to be convenient for consumption and beautiful. The silver tin foil on the yogurt lid is aluminum foil, which is sealed with aluminum foil and has the advantages of heat insulation, moisture-proof, hygiene, and long storage time. Aluminum foil's compatibility with heat-seal coatings, coupled with its excellent thermal conductivity and stability, make it an ideal material for sealing all types of plastic milk containers. The silver tin foil on the yogurt cover is aluminum foil. The aluminum foil seal is not only heat-insulating, moisture-proof, hygienic, easy to open, and has a long storage time, but also improves the quality of the yogurt product. Milk cover foil is mainly made of 8 series alloy, such as 8011 cover foil. The 8011-o aluminum foil produced by Hongchang Aluminum is non-toxic, tasteless, safe and hygienic, with a clean surface and uniform color. It is very suitable for making yogurt lids. At the same time, the 8011 aluminum foil reaches A level for brushing, has excellent moisture-proof performance and high shading. Barrier ability, extending the storage time of yogurt.
Medicinal aluminum foil is generally made of electrolytic aluminum with a purity of more than 99% and is rolled. Aluminum has the advantages of abundant resources, low price, and easy processing. When used as pharmaceutical packaging materials, aluminum foil is the only metal material in the packaging materials. Aluminum foil is non-toxic, odorless, has excellent electrical conductivity and light-shielding properties, has extremely high moisture resistance, gas barrier properties and taste retention properties, and can effectively protect the packaged items. It is a packaging material that has yet to be replaced. Commonly used alloy numbers for medicinal aluminum foil: PTP medicinal aluminum foil: PTP medicinal aluminum foil is also called medicinal plate aluminum foil and capsule aluminum foil. It is mostly made of 8011-H18 aluminum foil or 8011-O aluminum foil. Blister medicinal aluminum foil: Blister aluminum foil is also called cold-formed medicinal foil. It is mostly made of 8021-O aluminum foil and is used for high-end high-end airtight, moisture-proof and light-shielding pharmaceutical packaging. The thickness is 0.04-0.065 mm; Medicinal tropical aluminum foil: Tropical aluminum foil is also called aluminum-plastic aluminum. Tropical blister packaging is equivalent to adding a cold stamped aluminum foil cover on the outside of a thermoformed plastic blister and PTP aluminum foil. 8021-O aluminum foil and 8079-O aluminum foil are mostly used, which are high-end packaging aluminum foils for pharmaceutical packaging; Advantages of medicinal aluminum foil: 1. High-precision printing, rich colors and clear patterns; plain foil can be printed online on automatic pharmaceutical blister packaging machines. 2. It has excellent light-shielding, moisture-proof, oxygen-blocking, moisture-proof, chemical stability and fragrance-preserving properties. 3. The protective layer has excellent high temperature resistance, and the heat sealing layer has good heat sealing performance. It can be heat sealed to PVC, PVC/PVDC, NY/AL/PVC and other composite sheets with good sealing performance. 4. Aluminum foil is used as the base material, which is easy to push or puncture, making it convenient for consumers to take. The packaged blister board is easy to carry, easy to transport, store and prevent contamination. 5. Suitable for high-speed automated production, and can provide products with different width specifications according to the user's packaging machine model.
Color-coated aluminum foil is an aluminum foil product whose surface has been painted or coated. The performance of aluminum foil is very stable, and the paint can be used for several years without fading. Color-coated aluminum foil has the characteristics of water resistance, steam resistance, light resistance, taste resistance, corrosion resistance, heat resistance, low temperature resistance, etc., and is not easily affected by the environment and temperature. Therefore, it is often used in food, medicine, beverages, cosmetics, spices, etc. to prevent items from absorbing moisture, oxidation, volatilization and deterioration. When aluminum foil is placed in the air, a dense oxide layer forms on the surface. If the oxide layer is not dirty, the ink will have good adhesion to it. In order to improve the adhesion between the ink and the aluminum foil surface, corrosion cleaning must be performed before printing. Coating treatment eliminates lubricant contamination and enhances the adhesion between ink and aluminum foil surface. When performing color printing, since the aluminum foil paper itself has color, in order to ensure the correct restoration of the ink hue, the background color must be printed before printing, and the background color is usually white ink. Color-coated printed aluminum foil commonly uses 1000, 3000, and 8000 series alloy numbers, including 1100, 1070, 3003, 3004, 8011, 8021, 8079 and other alloy numbers. Color printed aluminum foil is suitable for a variety of industries, including the food and beverage industry, pharmaceutical industry, personal care and cosmetics industry. The foil is printed using high-quality rotogravure and flexo printing, giving the packaging a vibrant appearance. Hongchang Aluminum is a professional aluminum foil manufacturer specializing in the production of 1-8 series aluminum foil, including printed aluminum foil, colored aluminum foil, packaging aluminum foil, insulating aluminum foil, etc. The product range is complete and the specifications can be customized according to customer needs.
Aluminum plates whose purity can reach over 99.00% are called pure aluminum plates. Commonly used alloy codes for industrial pure aluminum plates are 1050, 1060, and 1100. Among all aluminum plate series, the pure aluminum plate series contains the most aluminum. Series 1 aluminum plates have the advantages of low density, easy processing, corrosion resistance, good electrical and thermal conductivity, strong reflectivity, and low price. They are widely used in lighting fixtures, reflectors, decorations, chemical industry containers, heat sinks, signs, electronics, Lamps, nameplates, electrical appliances, stamping parts and other products.
Household aluminum foil is mainly used for cooking and decoration. In terms of cooking, aluminum foil can be used to store food, cover baking surfaces, wrap meat and other foods to prevent them from losing moisture while cooking, it can also be used to line baking sheets to keep things tidy, or for scrubbing dishes or baking dishes. rack to remove stubborn stains and residue. Household aluminum foil is also called aluminum foil, kitchen aluminum foil, and food packaging aluminum foil. It is produced from raw material aluminum ingots through main processes such as casting, cold rolling, foil rolling, slitting, and annealing. It has excellent performance and stable quality. Household foils usually use 1235 aluminum foil and 8011 aluminum foil, which have the advantages of food grade, flat plate shape, clean surface, no oil stains, bright lines and other inclusions, safe and hygienic products, and high elongation rate. Performance advantages of household aluminum foil: Aluminum foil food packaging is beautiful, lightweight, easy to process, and easy to recycle; 1. Aluminum foil is non-toxic, tasteless, safe and hygienic 2. Excellent barrier properties, strong air barrier properties, antioxidant, waterproof, and moisture-proof; helps maintain the aroma of food and keeps food fresh for a long time. 3.
