Plastic bags are widely used all over due to its versatility and it is almost impossible to do without it. Unfortunately, plastic has adverse effects on the environment and we are forced to look for cost effective alternatives for it. If you company requires the use of plastic bags and you are looking for a cost effective substitute, read to know how to make a substantial saving on your garbage bag spends.

How to Measure!

It is necessary to know what Garbage bag fits your bin. The undersized bag may not be able to utilize the complete bin area and oversized bag might get wasted

How to measure bags?

Square Container – Layflat (Note: Depth is shorter of the 2 sides.)

  • Bag width = container width + container depth + 5cm for looser fit
  • Bag length = container height + container depth + 10cm to cover contents and tie the bag closed
  • Example: Container size: 35cm(W) X 25cm(D) X 60cm(L)
  • Bag size: 65cm X 95cm

Round Container – Layflat

  • Container Circumference = Diameter x 3.14
  • Bag width = container circumference divided by 2 + 3cm for looser fit
  • Bag length = container height + container diameter + 10cm for over hang
  • Example: Container size: 31cm(D) X 54cm(L)
  • Bag size: 65cm X 95cm

What is Recycled Plastic?

So what is the alternative to this? Most of us think it is recycled plastic bags. While this is a good option, especially for the environment, recycled bags are not exactly cost effective. They are manufactured from used/reused congregated plastic waste. Cleaning and preparing used plastics takes a lot of water, energy, and effort.

Additionally, as they are made out of plastic waste, to maintain their agility and strength, it is necessary to keep their thickness at more than 60 microns. As a result, the recycled plastic bag gains about 50% more weight than those of virgin bags.

Drawbacks of Recycled Bags

  • Strength is substantially lesser than virgin bags
  • Generates unpleasant odor
  • Less durable and lesser shelf life than virgin bags
  • Needs more space for storage
  • Poses inconvenience while transporting
  • Do not meet the established hygiene standards
  • They are legally banned in most cities as they are non-biodegradable
  • These bags, generally  can be produced in black color only

What are Biodegradable Bags?

Oxo-Biodegradable bags are a technically advanced and innovative range of product that is environmental friendly. These bags are manufactured from polymers like HDPE, LDPE and LLDPE, which degrade quickly making them environment friendly as well.

Apart from the environmental benefits, these bags are also cost effective. By adding specific ingredients and basic polymer, plastic bags can easily be converted into Biodegradable ones, providing a safer and cost effective solution. They can also be made with the same machine and workforce of a virgin plastic bag.

Since they are made of raw ingredients, it is possible to maintain the strength of the bags. In fact, there is no difference in quality, texture, or strength between regular and Biodegradable plastic. Moreover, it is even possible to customize the thickness of the bags as per the individual’s needs.

Advantages of Biodegradable Bags

  • The strength factor is consistent and these bags are highly dependable
  • They do not carry an unpleasant odor
  • They have a longer shelf life
  • Biodegradable Virgin bags are more hygienic
  • They are less toxic and degrade quickly and therefore are environmental friendly
  • They need lesser storage space
  • They can be transported easily
  • They can be manufactured in different colors
Type Material Size (cm) Thickness (Microns) Weight of 1 Bag (gm) No. of Pcs/KG Pcs/20Kg Bundle Indicative Price/KG Price per Piece % Reduction Remarks
Recycle Heavy Duty LDPE                                   65x95 80 92.8 10.77 215 4.2 0.39
Virgin Heavy Duty HDPE 50 58 17.24 345 7 0.40
Virgin Domestic Pack HDPE 30 34.8 28.73 575 7 0.24 60% Suggested

* 30 micron in HDPE Virgin material would have strength approximately equal to that of an 80 micron Recycle bag

“As it is evident, that using Biodegradable Virgin bags is economic and safe option for any business. Change to Biodegradable bags and make a considerable saving!”

Plastic Terminology

The definitions of the following terms only include information related to the packaging industry; the terms may have other definitions as well. 

  • Biodegradable – capable of being decomposed by bacteria or other biological means
  • Compostable – capable of being used as compost
  • Extrude – to form plastic with a desired cross-section by forcing it through a die
  • Extruder – a machine that transforms resin into film and another name for a manufacturer of film
  • Film – a thin sheet of plastic that can be converted into plastic bags or tubing
  • Mil – .001 inches (i.e. A Thousandth of an inch); not a millimeter
  • Microns – A Thousandth of a centimeter
  • Poly Bag – a plastic bag made of polyethylene
  • Polyethylene – a plastic polymer of ethylene used for packaging 
  • Post-Consumer Recycled Poly – recycled from household waste (ex. checkout bags taken returned to the supermarket and placed in the recycling bin)
  • Post-Industrial Recycled Poly – recycled from manufacturing waste (ex. scraps left over after trimming bags down to size)
  • Flexo Printing  Regular block colors printing commonly used for Grocery Bags
  • Roto Gravure Printing – More precise printing made with the help of Steel rollers for more perfection. Commonly used for processed food items like Chips or Cookies to keep them fresh.
  • Process Printing – high end screened prints and “photographic type” images
  • Recyclable – able to be recycled
  • Recycle – to treat or process used or waste materials so as to make suitable for reuse
  • Resin – small beads of raw plastic used to produce plastic film
  • Virgin Poly – polyethylene that has no additives and has not been recycled
  • Width – the side of the bag or tubing that opens
