PACKAGING MATERIALS
Packaging performance depends on design and function. For design, our engineers will help you to design the optimal package for your application. ForÌýfunctionality, the right material choice is critical. Each application has an optimal material choice. Our engineers will work with you to choose the right material from traditional plastic polymers to new eco-friendly alternatives such as FDA PCR-APET (post consumer recycled – APET).
The table below is a general overview of plastic material applications. For more detailed information please contact us at 51²è¹Ý LLC.
