Coroplast ® has gone through an extensive material qualification and testing program to ensure the proper combination of process, materials and adhesion levels is well suited for our customer’s packaging needs.
Based on the samples tested, the results indicate good adhesive integrity throughout the extreme temperate ranges. Abrasion protective qualities were good providing parts were protected water saturation. Water saturated samples negate the protective qualities of spunbond and lead to testing failure and scuffing of class “A” surfaces almost immediately. As with all packaging applications, simulated transport testing should be conducted utilizing the actual packaging and parts to be protected as the configuration of the parts can play a significant role in the success or failure of the protective packaging.
