Waste bags & Sacks
Introduction
|
'Waste bags and Sacks' are flexible material used for lining litter or waste containers or bins. This serves to keep the container sanitary by avoiding container contact with the rubbish. After the bag in the container is filled with litter, the bag can be conveniently pulled out by its edges, closed, and tied..

It is widely used for collection, storage, disposal and handling of different waste stream such as clinical, recycling, domestic, hospital, kitchen waste etc. Most bags nowadays are made out of plastic. 'Waste bags' also known as garbage bags, rubbish bags, refuse sacks, bin liner & can liner etc.

History of Waste (Garbage) bags
The familiar green plastic garbage bag (made from polyethylene) was invented by Harry Wasylyk in 1950.Harry Wasylyk was a Canadian inventor from Winnipeg, Manitoba, who together with Larry Hansen of Lindsay, Ontario, invented the disposable green polyethylene garbage bag.
Garbage bags were first intended for commercial use rather than home use - the bags were first sold to the Winnipeg General Hospital. However, Hansen worked for the Union Carbide Company in Lindsay, who bought the invention from Wasylyk and Hansen. Union Carbide manufactured the first green garbage bags under the name Glad Garbage bags for home use in the late 1960s.

How Garbage bags are made?
Garbage bags are made from low density polyethylene, which was invented in 1942. Low density polyethylene is soft, stretchy, and water and air proof. Polyethylene is delivered in the form of small resin pellets or beads. By a process called extrusion, the hard beads are converted into bags of plastic.
The hard polyethylene beads are heated to a temperature of 200 degrees centigrade. The molten polyethylene is put under high pressure and mixed with agents that provide colour and make the plastic pliable. The prepared plastic polyethylene is blown into one long tube of bagging, which is then cooled, collapsed, cut to the right individual length, and sealed on one end to make a garbage bag.

Popular Waste bags & Sacks
- Black Refuse sack range:- These bags are slightly larger than the garbage
bags. They are also used to collect garbage. A medium density blend gives great
puncture resistance despite being much thinner and so much cheaper for you!
- Refuse, Dustbin & Wheelie bin sacks:- These bags are used with garbage
bins for collection of garbage. Sturdy and strong, they are available in Black,
Blue, Grey, Green and White Colour. Enables instant identification of bag
contents. Leak-proof: protects against messy spills. Waste bins stay clean and
sanitary.
- Extra strong Aggregate sacks:- The heavy duty household rubbish bag and
the ultimate tough aggregate sack guaranteed to hold 40kg. Ideal for bagging
builders rubble, gravel, sand, soil etc. Extremely strong: hard-wearing and
puncture resistant, can be used many times.
- Pedal, Square & Swing bin liner:- Liners for every shape of bin.
Normally in a thin white material but also now in a clear bag for contents
identification.
- Special waste sacks:- Specialist bags for recycled and hazardous
materials. Gardeners use the green recycling sack and the wheelie bin liner.
Also includes extra thick Asbestos and Clinical Waste sacks pre-printed with
the correct statutory information.
- Biodegradable waste sacks:- Ideal to help towards a better environment.
Biodegradable waste sacks will biodegrade in your compost or in landfill.
- Clear waste bags:- Medium to Strong clear polythene bags that enable
instant identification of contents. Ideal for separating products or materials
for recycling.
Select the right material for your Waste bags & Sacks
- HDPE (high density polythene) garbage can liners are a strong, thin,
material that is frosted in appearance. This material has excellent tensile
strength but is punctured by sharp object easier than other materials. It is
ideal for use in environments where sharp corners are not a large part of the
refuse going into the garbage can liner. The smaller sizes are ideal for office
use. The larger sizes, which have increased thickness as compared to the
smaller sizes, are great for heavy loads that don't have many sharp objects.
- LLDPE (liner low density polythene) can liners are typically thicker than
HDPE and they offer good tensile strength, but less than HDPE, as well as
better puncture resistance when compared to HDPE. This material also has a
softer feel than HDPE. LLDPE is also ideal for office trash cans. This material
is also an economical choice for larger garbage containers with refuse that has
some sharp corners but is not extremely heavy.
- LDPE (low density polythene) material has been the standard for all
plastic bags since the beginning of the plastic bag industry. It is generally
thicker and softer in feel than LLDPE. It has good puncture resistance but also
has less tensile strength than LLDPE. For this reason, LDPE trash can liners
are usually made to be much thicker than the other types of poly material and
is also usually made from recycled plastic. Because of the thickness, this
material can be an excellent choice for heavy duty applications.
- Biodegradable waste sacks:- Ideal to help towards a better environment.
Biodegradable waste sacks will biodegrade in your compost or in landfill.

Creative Idea - Turn your waste bags into fashion, Check!
Couple turn waste bags into fashion
A couple in India have found a solution to the problem of plastic bags
littering the streets of the country's capital, Delhi - by turning them into
fashionable handbags.
Anita and Shaleb Ahuja employ people in the slum areas of the city to collect
the bags, which are a major problem throughout the country - often ending up
polluting the environment, littering streets and blocking drains.
The discarded bags are washed and sorted before being turned into plastic
sheets, which are then refashioned into the handbags.
"We were already into waste management, and we were getting a lot of
plastic waste," Mrs. Ahuja told BBC World Service's Outlook programme.
"That's when we decided to try and find a solution to this big
problem."Potential
Mrs. Ahuja and her husband established a non-governmental organisation called
Conserve to launch their idea, using their life savings to set it up.
Plastic bags are such a problem in India that one state, Himachal Pradesh, has
even banned them outright.
In Delhi, however, Conserve employs rag pickers to scour the city's waste
dumps.
Some women snip at the handles of the bags to make them into sheets; others
wash them in water and detergent and hang them on a clothes line.
These are then moulded together into single sheets of thick, durable plastic,
and stitched into bright, colourful handbags.
Mrs. Ahuja said the idea came by accident, when a friend making fabric bags
asked for a few sheets of the plastic, and designed the first bag."I showed it to my friends, and they liked it very much," she said.
"That was the time that it struck me that it had potential."It has now become a highly successful enterprise, employing 300 people and with
a turnover of around $150,000."Lots of women come to me and say they also want to work here," said Gita Pande, one of the Conserve workers.
"I don't want to travel out of a slum to work I feel safe here, so I don't mind working here.
"I'm also doing something that's useful. Polythene bags clog our drains. Cows eat them and get choked. By making them into bags, they get used, and unemployed people get jobs.
"I feel it's good for the municipality as well, because we are taking the garbage off the streets, and they don't have to clean them." The Ahujas are now trying to convince the Indian Ministry of Culture to recognise what they are doing as a craft.
However, Mr. Ahuja explained that they are not having much success.
"They say that if it's not 500 years old, it's not a craft," he said.
"It is absolutely frustrating."
