Purity tubes can be manufactured as Monolayer or EVOH Multilayer. The type of tube that is manufactured is largely dependent on the type of product that is being packaged. Unless compatibility trials have been conducted on monolayer tubes and found to be successful, we strongly advise that the following products are packaged in Multilayer tubes:
- SPF
- Essential Oils
- Organic Ingredients
- Clear Gel products (Face Wash, Body Wash, Hand Sanitizers)
