When you open a cap on a product, you probably do not give much thought to the material it is lined with. Your customers might not consider it much either—until it’s the wrong material for the job. In that case, you’ll regret not researching the available options before proceeding with production.
These are some of the materials commonly used in the best cap lining machines in St. Paul, MN.
Foam Linings
These liners are typically applied using a spray mechanism and are made from either polyethylene or polypropylene. They are suitable for general use in various products and offer cost-effectiveness. However, they are not well-suited for aggressive chemicals or solvents. Polyethylene is generally more economical, whereas polypropylene provides a stronger layer of protection and greater resistance to certain chemicals.
Teflon
Teflon is well-documented for keeping even sticky, viscous products from adhering to it. The substance – known also as polytetrafluoroethylene – offers strong resistance to chemicals and protection for products contained or sealed with it. Teflon is much more expensive than other common sealants, making it less suitable for less aggressive chemicals or more general use.
Plastisol (PVC)
Plastisol liners are excellent options for beverages, sauces, and other fluid products. They offer superior chemical resistance to other types of plastic, making them ideal for cleaners and other harsh substances. There are some environmental concerns, though, as the mixture generally contains primarily PVC.
Aluminum
Aluminum is lightweight and a great non-plastic option, perfect for induction sealing. It does require heat for proper sealing, so it may not be appropriate for all applications.
While aluminum itself may not be appropriate for many sealant applications, it can be used as part of a multilayered sealant. Today’s most popular pressure-sensitive sealants are a prime example of this.
It is important to remember that different containers will need different materials for their liners. The best cap lining machines in St. Paul, MN,will allow you to change materials between batches, giving you the ultimate freedom to customize your process.
