Caps and closures are a small piece of the overall package, yet are highly engineered components, requiring an equally well engineered masterbatch. There are many factors to be taken into consideration when developing a colorant for a closure, and we go through great lengths to understand all of these factors before we formulate our color concentrates.
Maintaining dimensional stability is often a key component in a successful closure colorant, and we have an extensive list of pigments and additives to allow for the most dimensionally stable caps under your process conditions. Prototype molding and measurement equipment allow us to pre-screen pigment and additive combinations before we send a sample for you to test. Pigment and additive selection can significantly impact dimensional stability of the closure. Understanding the impact different pigment chemistries can have on shrinkage and warpage characteristics of a closure is critical, and Penn Color’s pre-screened pigment and additive combinations will ensure all performance guidelines are met.
Closures with direct food or beverage contact put an extremely high value on organoleptic properties. Again, we have extensive knowledge in raw material selection, as well as the ability to analytically test for this constantly evolving property. Our regulatory group has vast knowledge of the ever changing regulatory guidelines, whether it’s for EU, FDA or any other regulatory statute. We’ll create and supply all the proper documentation that you request to accompany the masterbatch sample.
Additional value or expertise that we can add to the formulation include:
We look forward to working with you on your next closure opportunity!
