An Alternative to Glass
Plastic Bottles
Have any tests been run in plastic? Was it unsuccessful and why? What type of plastics?
Plastic containers have been developed for a variety of applications across many different industries over the years. There are many different types of polymers used in the creation of these containers to help fill the demands for the various applications. Polymers offer a variety of properties, each having different levels of importance with different users depending on the application. Some users may have flexibility within their product formula or filling process and therefore focus on economical containers while others may need containers that are stronger, autoclavable, transparent, sterilized, etc., therefore requiring more specifications. DWK Life Sciences can help with polymer selection through comprehension of the customer’s product, goals, and adaptability. Several questions should be posed to gather this understanding. Some examples include: What is the container size and physical design: Narrow mouth vs. wide mouth, tall vs. short, etc.? Must the package be transparent, translucent, opaque or colored for either marketing or light protection? Are there specific shipment and storage conditions such as refrigeration, freezing, exclusion of light, etc.? Are there governmental regulations pertaining to the product? How is the product going to be dispensed by the user?
Many things govern polymer suitability for package use. These include: ■ Permeation / Barrier ■ Sorption Characteristics ■ Chemical Resistance ■ Stress Crack Resistance
■ Rigidity / Flexibility ■ Impact Resistance
■ Sterilizability ■ Recyclability ■ Temperature Resistance
