When it comes to product packaging in plastic bottles, jars and jugs, resin characteristics and compatibility with your specific product are critical. O.Berk has compiled some general guidelines to help.

Packaging your product in a plastic container goes beyond color, shape, and marketability – as different plastic resins have their own distinct characteristics that can dramatically impact a successful package. It's a critical choice that will either protect, or affect a product.

To help guide the decision process, O.Berk has come up with a quick and easy to read "Plastic Packaging Cheat Sheet"! It is an indispensable reference to help clarify plastic characteristics that are often confusing. In just a few short moments you can learn more about the 7 major categories of plastics used for packaging, their physical characteristics, and the potential for a reaction with your product. The Cheat Sheet will tell you what you need to know... and how to avoid pesky problems.

Remember, even with these guidelines, the only way to know for sure is to test a specific product with all of the different packaging components for compatibility as each product and package combination is unique and can react slightly differently.

Note that Essential Oils are always a special case. Avoid using PET containers to package products that contain essential oils greater than 5% or fragrance oils greater than 15%. Should oil percentages exceed these respective levels then use of glass should be considered.
