Surlyn Skin Packaging Film with No Adhesive

A: Skin packaging (not to be confused with blister packaging) is made by putting surlyn or poly film over a product and heating it after it has been placed on a backer. Backers are flat boards made from materials like blister-board, paper, or plastic.

A: Skin surface lipid (SSL) film is a mixture of sebum and keratinocyte membrane lipids, protecting skin from environment. Its composition is unique for the high percentage of long chain fatty acids, and of the polyterpenoid squalene, absent in other human tissues, and in non-human Primates sebum.

A: Durability: Urethane is generally less durable than Surlyn. These balls may be more prone to cuts and scuffs, particularly if you often hit trees, cart paths, or other hard surfaces. Price: Urethane golf balls tend to be more expensive because they're often used in higher-end, tour-level golf balls.

A: Surlyn is used for a variety of orthotic and prosthetic applications, including cranial helmets, scoliosis braces, body jackets, flexible prosthetic sockets, check sockets, upper limb orthoses, and face masks for sports and burn treatment.

A: Thermosetting plastics and thermoplastics are both polymers, but they behave differently when exposed to heat. Thermoplastics can melt under heat after curing while thermoset plastics retain their form and stay solid under heat once cured.
