PE Coating
Polyethylene (PE) coated cardboard is suitable for packaging applications where moisture barrier properties are important. The PE coating also offers a simple but efficient way to seal the package. PE coatings can be one or two-sided and there are three different types of PE coating available: LDPE, LDPE Super Seal and HDPE. The LDPE is the most used product for frozen products. It offers a good combination of barrier and weldability properties. LDPE Super Seal has better heat sealing properties than LDPE. The barrier properties are marginally lower. HDPE has a higher temperature limit, is more resistant to wear and has better barrier properties than LDPE. HDPE coatings are normally applied on the back. All PE coatings are available in white, brown or black pigmented versions.
