Surlyn vs. Skin Poly Film

Skin packaging has become one of the most preferred packaging solutions for a wide range of products. Whether you are packaging food items or hardware tools, you will find skin packaging an appropriate packaging option. However, you might not be sure if you need to use a surlyn film or skin poly film for product packaging.

Both these films are seemingly appropriate for similar applications, but the fact of the matter is that each type is appropriate for specific applications. You are going to have to know which film fits your requirements in the best way.

In this article, we are going to talk briefly about both films.

What is a surlyn film?

Made by Dupont™, Surlyn® skin packaging films are an even better alternative to clamshell and blister packaging. When you need to apply skin packaging on coated boards, and ultra-high-clarity and strength are a must, you can consider using this skin packaging option. This film emerges as the best solution when it comes to packaging food.

What is Skin Poly Film?

You can use skin poly film in the production of skin packs. You may use it for similar applications and surlyn. This film is a type of low-density polyethylene film (LDPE).

The two varieties available in skin poly wrap are POLY-WRAP® PW-500 and POLY-WRAP® PW-242. POLY-WRAP® PW-500 features high strength, while POLY-WRAP® PW-242 offers superior clarity. It means that you are going to have to choose between strength and clarity while picking the type of skin packaging film.

If you want to choose both the strength and clarity, you can consider picking a surlyn film as it offers both features in one film.

How are both films used in the packaging?

The process of skin packaging involves putting surlyn or poly film over a product and heating it. The product must be placed on a backer. Backer is a flat board, usually made of materials like blister-board, paper, and plastic.

The most common applications that use skin packaging may include fish packaging, hardware packaging, computer component packaging, electrical component packaging, and many other types of products.

This film serves nicely when the customers have to see the original product before purchasing it. Surely, the retailers are not going to let the customers tear apart the outer packaging just to check the product. Skin packaging allows customers to have a thorough look at the product without opening the package.
