Biodegradable products

Polybags Ltd. now manufacture and stock a wide range of eco-friendly green packaging and biodegradable products to suit your needs and help towards a better environment (both PolyBio and Biodegradable). These include kitchen waste and refuse bags, bin liners, carrier bags and standard bags developed in Polybags laboratories in conjunction with the Polymer Research Department at the London Metropolitan University.

Why environmental bags has become a popular search term

Beginning last year, Alibaba's logistics arm, Cainiao, attached a host of other courier and e-commerce companies in shifting toward environmentally friendly practices, including hybrid and fully electric delivery vehicles, tape-complimentary boxes, electronic invoices, and biodegradable packaging materials.

Eco-Friendly Packaging in Your Business

We live in the era when“green” has already become the new black. With a growing need for reducing their ecological footprint, more and more companies and organizations turn to eco-friendly packaging solutions. Apart from the fact that such a switch contributes to creating a healthier environment, it also reduces the financial packaging costs professional ventures invest when selling and shipping a product.

Only the following bag brands are acceptable to put in your food and yard waste bin. These logos also identify compostable bags accepted in Seattle's food and yard waste bins.

"Biodegradable plastic bags are in plenty cases manufactured from gross oil, requiring carbon-based production processes and are emitting Carbon Dioxide or methane when degrading," he said.

Scientist In United Kingdom Creates Biodegradable Plastic From Prickly Pear Cactus

"In this case the nopal cactus has certain chemical properties with which I view it could be feasible to acquire a polymer, that if it was attached with a few other substances, all of them normal, a non-toxic biodegradable plastic would be obtained. The process is a mixture of compounds whose base is the nopal. It's totally non-toxic, all the materials we use could be ingested both by animals or humans and they would not cause any hurt.”

Market Overview of Biodegradable Packaging:

Bioplastics

Bioplastics can take different length of times to totally compost, based on the material and are meant to be composted in a commercial composting facility, where higher composting temperatures can be reached and is between 90-180 days. Most existing international standards require biodegradation of 60% within 180 days along with certain other criteria for the resin or product to be called compostable. It is also important to make the distinction between degradable vs. biodegradable vs. compostable as often these terms are used interchangeably.

Biodegradable Plastic

Biodegradable Plastic is plastic which will degrade from the action of naturally occurring microorganism, such as bacteria, fungi etc. over a period of time. Note, that there is no requirement for leaving "no toxic residue", and as well as no requirement for the time it needs to take to biodegrade.

Recycling is also important for the environmental and for that we also have a recycled bags page with interesting information.

Degradable Plastic

Degradable plastic includes all classes of degradable plastic including the biodegradable and compostable. However, plastic that is not biodegradable or compostable usually use the label Degradable plastic. Most of the products using the label Degradable plastic, degrade as result of physical and chemical impact. Biological activity is not a significant part of the degradation of these products, or the process is too slow to earn the classification Biodegradable or Compostable.

Types of Degradable Plastic

Starch-based

Some degradable plastic products are based on starch derived from maize. These materials predominantly require an active microbial environment such as landfill or composting before they will degrade some will totally degrade in such an environment but others will only perforate, and the plastic component will not degrade. The remaining plastic particles can e harmful to soil, birds and other wildlife. Whilst using renewable ingredients may seem attractive in principle, they do not offer the best way forward.

Aliphatic

Another type of degradable plastic uses aliphatic polyesters, which are relatively expensive. In the same manner as starch, they rely on microbial activity in compost or landfills before they will degrade.

Photo-degradable

These will degrade when exposed to sunlight, but will not degrade in a landfill, a sewer, or other dark environment.

Oxo-bio-degradable

The products above degrade by a process of HYDRO-degradation, but the most useful and economic of the new technologies produces plastic, which degrades by a process of OXOdegradation. This technology is based on a small amount of pro-degradant additive (typically 3%) being introduced into the conventional manufacturing process, thereby changing the behavior of the plastic. This does not rely on microbes for the degradation of the plastic, which starts immediately after manufacture and will accelerate when exposed to heat, light or stress. This process is irrevocable and continues until the material has reduced to nothing more than CO2 and water. It does not therefore leave fragments of petro-polymers in the soil.

Biodegradable or Biodegradeable?

It is very common to misspell biodegradable as biodegradeable (please take note yourself as some of our domains are actually misspelt!) and the same happens with degradable as degradeable. In fact when written down the word biodegradable often looks like an incorrect spelling and has been known to be corrected to biodegradeable by some overzealous and missinformed editors. So, now you know if someone tells you otherwise stick out your guns!
