The uses of packaging foil have grown over the past 100 years to a nearly endless count. From Christmas tree ornaments to spacecraft insulation, TV dinners to medicine packets—aluminum foil has, in many ways, improved both our products and our lives.
The “shiny” side of aluminum foil is 88 percent reflective, making it one of the best and most efficient insulators to solar heat.
Foil wrappers are one of the oldest applications of packaging foil, having been used for chocolate since 1911 right up to the present day as well as having been used for butter, cheese and tobacco products for a long time. Many of these products are laminated or coated with paper or plastic respectively and are available as sealed or adhesive wrappers, which are impervious or very nearly so and guarantee the authenticity of the contents

Heat seal temperature is an important factor affecting the heat seal strength. The temperature is too low, so that the bonding layer can be well sealed with the PVC film, and the bonding between the adhesive layer and the PVC film is not strong. If the temperature is too high, it will affect the drug. Therefore, the reasonable heat sealing temperature is usually between 150 and ~160.
