What is Skin Packaging?

Skin packaging uses heat sealing to vacuum form film over the product as efficiently as possible. Heat sealing is the central procedure of skin packaging because it can work with a wide variety of materials using an automated process. Manufacturers use equipment to coat the backing material known as skin board—usually paperboard or corrugated cardboard—with specialized adhesive compounds. The film is heated and applied to the product and its backing.  When the heated film comes into contact with the backing substrate, it forms an airtight seal around the product. Then, the platform containing the heated film is lowered over the product, a vacuum draws the film down to the substrate and around the product, which results in a neat and attractive look. Skin packaging is a lower-cost packaging option used to display and protect products. Skin packaging provides lockdown product protection, product visibility, and tamper evidence.

Every skin packaging design consists of three vital components:

  • The skin board: This is the backing substrate and is often made from paperboard or corrugated cardboard. Determining the proper skin board for your product depends on a number of factors, including product size, weight, durability, and material costs. Skin boards can come in a variety of different grades and thicknesses, and they can be made from recycled material and other eco-friendly substrates.
  • The film: Co-packagers use a thermos-form plastic film. Skin packaging film is manufactured from a surlyn resin engineered to adhere only to the coating on the skin board.
  • The machine: Skin packaging machines ensure that the film and skin board are sealed together properly and that the film’s shape follows the product’s contours. After the board has been coated with a layer of heat seal dispersion substance, the film is tightly clamped in place by a frame underneath the heater. At the start of the machine’s operational cycle, the film is heated, and the clamping frame is drawn over the skin board. Then, a vacuuming operation ensures that the film makes contact with the optimal surface area of the board, and then the film and substrate almost instantly bond together.

Skin packaging is commonly used in retail environments. For example, skin packages that contain small parts or accessories are often placed upon racks in store aisles to allow customers to see the product without having to open the package. But skin packaging has many additional applications beyond retail. Skin packaging is suitable for all technical, medical and hygienic products made of metal or plastic as well as valuable tools, cutlery, hardware store goods or office items.
