Applications of Hot Sealing Aluminum Foil
8011 Hot Sealing Aluminum Foil for Yogurt Cup Lids
For yogurt cup lids, the hot sealing aluminum foil used needs to have good flexibility and plasticity to ensure a reliable seal on the cup's opening. Typically, the 8011 aluminum foil used has a thickness ranging from 0.01 to 0.05 millimeters, with a smooth surface free from scratches, wrinkles, or other defects. This type of foil requires excellent sealing properties, good antibacterial performance, and outstanding puncture resistance to prevent leaks or contamination during use.
1235 Hot Sealing Aluminum Foil for Pharmaceutical Packaging
For pharmaceutical packaging, the 1235 hot sealing aluminum foil must meet pharmaceutical-grade sterility requirements and have a clean and flat surface. Generally, high-purity aluminum materials from the 1000 series, such as the 1235 alloy, are used, with foil thicknesses ranging from 0.015 to 0.2 millimeters. This foil offers good puncture and peel performance, ensuring easy handling and providing effective sealing.
Medical Grade Heat Seal Foil Tape
Medical-grade heat seal aluminum foil tape is an efficient, cost-effective, and reliable sealing solution, widely used to seal microporous plates, holes, and channels in diagnostic equipment. This tape can be used over a wide temperature range, exhibiting peelable, puncture-resistant, and solvent-resistant properties, and can adhere firmly to various substrates to ensure sealing performance.
8011 Hot Sealing Aluminum Foil Bags for Food Packaging
8011 aluminum foil used for food packaging in hot sealing aluminum foil bags is typically laminated with plastic films (such as PE, PET, etc.), with foil thicknesses generally ranging from 0.04 to 0.09 millimeters. These foil bags have excellent air and liquid barrier properties, effectively blocking oxygen and moisture, making them suitable for refrigeration and freezing environments from -30°C to 100°C. The heat-sealed edges of the bags are secure and aesthetically pleasing, free from burrs, ensuring complete isolation from the external environment and preserving the freshness and quality of the food.
Related Questions about Hot Sealing Aluminum Foil
What temperature do you seal aluminum foil?
Sealing Temperature: The temperature for sealing aluminum foil depends on the specific application and type of sealing material. Generally, for packaging applications, the temperature range for hot sealing aluminum foil is between 150°C and 220°C (302°F to 428°F). The exact temperature may vary based on the foil's thickness and the type of adhesive or laminate used. Adjusting the temperature is crucial to ensure a strong and reliable seal without damaging the foil or packaging material.
Can aluminum be heat sealed?
Heat Sealing Aluminum: Yes, aluminum can be heat sealed, but it requires a heat-sealable coating or laminate. Pure aluminum foil itself cannot be directly heat sealed; instead, it is typically coated with a heat-sealable material that allows it to adhere during the sealing process. This is commonly used in food and pharmaceutical packaging.
Can aluminum foil work as a heat shield?
Heat Insulation: Aluminum foil is indeed an effective heat insulation material. It reflects radiant heat rather than conducting it, making it very useful in applications where heat reflection is needed. In various industries, aluminum foil is used for insulation and protecting surfaces from high temperatures, such as in thermal blankets, cooking equipment, and barriers in certain electronic devices.
Can heat pass through aluminum foil?
Heat Transfer: Aluminum foil does conduct heat to some extent, but in many applications, its primary function is to reflect heat rather than conduct it. While heat can pass through aluminum foil, its high thermal conductivity means it can quickly transfer heat. However, due to its reflective properties, it is more effective at redirecting radiant heat than allowing significant heat transfer.
