(Why isn’t everybody using them?)
 
• Biodegradable Plastic Bags
It’s hard to imagine anyone in the developed world who is not, at least, aware of the pollution and landfill problems caused by plastic bags. Governments everywhere and at all levels are sponsoring campaigns against, and even taxing, the use of these environmentally un-friendly products.

Here are some of the points made in the Penrith City’s (NSW, Australia) campaign against the use of plastic bags. (link):
  • In Australia, it has been estimated that it costs governments and businesses over $4 Million per year to clean up littered plastic shopping bags.
  • Each year an estimated 6.67 Billion, or 36,700 tons of plastic bags are disposed of in landfill sites throughout Australia.
  • There are approximately 46,000 pieces of plastic floating in each square mile of our oceans.
  • Just 8.7 Grocery bags contain enough embodied petroleum energy to drive a car 1 Kilometre.
  • Normal Plastic Bags can last in the environment for up to 1,000 years.
  • Many countries throughout Europe have imposed an Eco-Tax on normal plastic bags. (Biodegradable plastic bags are exempt from such taxes.)
We are proud to announce that there is now a convenient, cost effective and environmentally friendly alternative to the normal plastic bag.

Since March 2004 we have been working with a manufacturer in China and Consultants Europe to make commercially available fully biodegradable plastic bags that comply with or exceed the requirements of the European Standard for biodegradability (EN 13432). This standard is generally recognised as one of the toughest in the world. It demands that the bags will biodegrade by 90% within six months. Compliance was finally certified in June 2006 after a series of submissions and adjustments to the bag composition. We are proud to offer the results of our efforts - Symbio biodegradable plastic bags.

Special plastic resin is mixed with a biodegradable additive in a tightly controlled manufacturing process. The process was invented, and patented, by a Chinese Professor at a major University in China. Both the additive and the process are commercial secrets.

The bags have been successfully tested to a variety of Standards. These include:
  • International Standard ISO 14855 (Ultimate Aerobic biodegradability and disintegration of plastic)
  • American Standard ASTM D5338 (Determining Aerobic Biodegradation of Plastic Materials)
  • Chinese Standard QB/T2461 (Packaging biodegradable PE film)
  • Chinese Standard DB35/343-1999 (Biodegradable PE Film and Bag)
  • European Standard EN 13432

• Special considerations...
...for ordering and using our Symbio biodegradable plastic bags:

The minimum quantity per order is 1 x 20’ Container, with a minimum of 50,000 bags per print (100,000 for smaller bags).

For quotations, please supply the following information:

1. Type of bags required (e.g. T-Shirt Bags, Carry Bags, Rubbish bags etc.)
2. The size of the bags (width + gusset x length)
3. The thickness of the bags (microns, or weight per bag)
4. Quantity required
5. Is print required, if so, how many colours how many sides
6. The destination Port

The normal shelf life for unopened packages of biodegradable plastic bags is one year. Therefore, stock must be rotated. In order for the breakdown mechanism to activate, the biodegradable plastic bags must be exposed to the environment. The bacteria found in open air, water and soil will start the breakdown process. In open air, the biodegradable plastic bags will begin to break down and start to disintegrate after 7 to 8 weeks.
