Paper Bag

 

The first recorded historical reference to grocery paper bags was made in 1630 but the use of sacks only really started to take off during the Industrial Revolution between 1700 and 1800. Margaret Knight (1838-1914) was an employee in a paper bag factory when she invented a new machine part to make square bottoms for paper bags. Knight can be considered the mother of the grocery bag, she founded the Eastern Paper Bag Company in 1870. On February 20, 1972, Luther Crowell also patented a machine that manufactured paper bags.
Recycled paper
Paper recycling processes can use either chemical or mechanical pulp. By mixing with water and applying mechanical action the hydrogen bonds in the paper can be broken and fibres separated again. Most recycled paper contains a proportion of virgin fibre in the interests of quality. There are three main classifications of recycled fibre:-

Mill Broke or Internal Mill Waste — this incorporates any substandard or grade-change paper made within the paper mill which then goes back into the manufacturing system to be repulped back into paper. Such out-of-specification paper is not sold and is therefore often not classified as genuine reclaimed recycled fibre. However, most paper mills have been recycling their own waste fibre for many years, long before recycling become popular.

Preconsumer Waste— this is offcuts and processing waste, such as guillotine trims and envelope blank waste. This waste is generated outside the paper mill and could potentially go to landfill, and is a genuine recycled fibre source. Also includes de-inked preconsumer (recycled material that has been printed but did not reach its intended end use, such as waste from printers and unsold publications).

Postconsumer waste — this is fibre from paper which has been used for its intended end use and would include office waste, magazine papers and newsprint. As the vast majority of this paper has been printed (either digitally or by more conventional means such as litho or gravure), it will either be recycled as printed paper or go through a de-inking process first. Recycled papers can be made from 100% recycled materials or blended with virgin pulp.


Recycled papers
are (generally) not as strong nor as bright as papers made from virgin pulp. Recycled Kraft Paper Recycled Kraft Paper is very economical and offers many beneficial qualities. Sensitivity to the environment on the part of more and more people makes them willing to try this grade of paper.

Environmental information
Recycled Kraft paper is made from 100% recycled materials - old corrugated cartons (post consumer) and paper processing production waste (post industrial). It is biodegradable, easily recyclable in existing waste streams, and compostable.

How Recycled Kraft Paper is used:
It has successfully been used as newspaper bottom wrap, garment underlay paper, textile wrappers, interleaver, internal carton packaging, void filler or dunnage, dust covers, floor protection liners, carrier sheet, paint masking and box/tray liners. Other uses include bundling and stuffing. Recycled Kraft provides less tear and bursting strength and will break down more easily when exposed to friction or moisture when compared to Virgin Kraft Papers.
