Eco-friendly and reusable plastics

Reusable PE carrier bags, hard-wearing and reuseable PP Non-woven and woven bags. PET bags, made from recycled material.

Environmental-friendly

Degradable plastic products have now become available which harmlessly degrade at the end of their useful life. These fall into two categories:

  • oxo–biodegradable
  • hydro–biodegradable

Degradation begins with an abiotic process, followed by a biological process. Both types are compostable.

We highly recommend this type of product as they provide an environmentally sound alternative to standard polythene. Instead of taking few hundred years, these bags will degrade in landfill in approximately 18 months, leaving a non-toxic residue.

Re-usable plastic bags for everyday use

If you have already used them then you are probably aware of the benefits, but for others it is important for you to know the differences between these types of materials, before you can consider and choose the best option to suit your needs.

Polyethylene – PE or PP

What is the difference between PE and PP?

The general term "plastic bags" can be better specified as two grades of polyolefin, namely Low density polyethylene (PE) and polypropylene (PP). These two materials are still the least expensive and most used carrier bags. The cost of PE and PP are about the same – one can cost more than the other depending on market demand and availability.

PE has a low melting point, and PP has a higher melting point. In general PE becomes useless at temperatures above 90°C whereas PP can withstand temperatures up to 130°C. A second variation of PE is HDPE, or high density polyethylene. This material has a higher melting point than regular PE and can withstand temperatures up to 108°C. HDPE has a temperature advantage over PE, but it has the disadvantage of having a heavy haze and does not provide the see through properties of PE.

Woven and non-woven polypropylene – the differences

To make Woven PP you are first required to have continuous fibers. These fibers are then converted into fabric by using various types of looms (weaving or knitting).

In a spunlaid non-woven material the fibers are directly taken onto a moving web which arranges them randomly. The unprocessed web looks somewhat similar to cotton. This fibers on this web are then bound together thermally or mechanically.

The important technical difference between a woven and non-woven fabric is the strength. Woven fabrics can have much higher strength than that of NW of same weight. There are various other differences based on the method of manufacturing and material used.

PET bags – The new bag to have

These bags are made from recycled water bottles that are collected from all over the globe, shipped back to China and processed into a material suitable to create a non-woven PET Bag.
