Plastic Additives
Take a look at the types of plastic additives we use to enhance our polybags and polytube products.

Plastic Extrusion Process

During the extrusion process additives can be blended through the resin mix for specific purposes: 

Coloured Additives – for tinted or opaque polytube or polybags, available in a wide variety of colours.

UV Stabiliser – to increase the longevity of bags that may be exposed to sunlight, for example landscaping bags.

Resin Grades – some low slip and some high slip, depending on the application


"From initial phone enquiry through to pick up of the completed product, I can not fault Meridian Plastics and Martin in particular. Knowing very little about the specifics of what I was looking to have produced, Martin took great care and attention to detail to make sure I would receive exactly what I imagined. The products are of a far higher quality than the previous version that I had originally used, and were completed in a timely manner.
I can not have been happier with the products or experience, great job team... We will definitely be returning." ~ Kerry Thompson
