Type of bags
Tote bags
The archetypal tote is made of sturdy cloth,
perhaps with thick leather at handles or bottom; leather versions often have a
pebbled surface. Common fabrics include heavy canvas, possibly dyed, or treated to resist
moisture and mold. Jute is another traditional material, though
less popular. In recent decades, heavy nylon and other easy-care synthetics have
become common, although these may degrade with prolonged sun-exposure. Many of
today's inexpensive or free totes are often made from recycled matter, from
minimally-processed natural fibers, or from by-products of processes that
refine organic materials.
Sling bags
A messenger bag (also
called a courier bag is a type of sack usually made out of some kind of cloth (natural or synthetic), that is worn over
one shoulder with a strap that goes across the chest resting the bag on the
lower back Messenger bags are
often used by bicycle messages, though they are now also an urban
fashion icon.
Some types of messenger bags are called carryalls. A smaller version is often called a sling bag and are often woven cloth in south-eastern Asian
countries such as Thailand, Burma, Laos and Cambodia. Nowadays used mainly by Hill people in Thailand and called Yaam.
Bag pack
A backpack (also
called rucksack, knapsack, pack-sack, and pack) is, in its simplest form, a
cloth sack carried on one's back
and secured with two straps that go over the shoulders,
but there can be exceptions. Lightweight types of backpacks are sometimes worn
on only one shoulder strap.
Backpacks are often preferred to handbags for carrying heavy loads or carrying
any sort of equipment, because of the limited capacity to carry heavy weights
for long periods of time in the hands. Large backpacks, used
to carry loads over 10 kg (22 lbs.), usually offload the largest part
(up to about 90%) of their weight onto padded hip
belts, leaving the shoulder straps mainly for stabilizing the load. This
improves the potential to carry heavy loads, as the hips are stronger than the
shoulders, and also increases agility and balance, since the load rides nearer
the wearer's own center of mass.
In ancient times, the backpack was used as a means to carry the
hunter's larger game and other types of prey and as a way of easier transport
for other materials. In the cases of larger hunts, the hunters would dismember
their prey and distribute the pieces of the animal around, each one packing the
meat into many wrappings and then into bags which they placed on to their
backs. The bag itself was made up of different animal hide and skin (depending
on what sorts of animals were in the area) and sewn together by animal
intestines, which were woven together tightly to make a sturdy thread-like
material.
Handbag
The term "purse" originally
referred to a small bag for holding coins. In British English, it is still used
to refer to a small coin bag. A "handbag" is a larger needed accessory
that holds items beyond currency, such as a woman's personal items and
emergency items to survive on. American English typically uses the terms
"purse" and "handbag" interchangeably. The term
"handbag" began appearing in the early 1900s. Initially, it was most
often used to refer to men's hand-luggage. Women's accessory bags grew larger
and more complex during that period, and the term was attached to the women's
accessory. Handbags are used as fashion accessories
as well as functional ones.
Causes of heavy schoolbags
Heavy bags is a common issue to
the old days and to the present year. It is a big problem to children growth.
It’s neither health issues relate problems can either lead to permanent issues
or severe injuries. In reality, children are spoiled and nurtured by their
parents. Teachers always do their best to have their student’s discipline.
Having an untidy bag can put on extra weight in the bag. It can also lead to
more books compiled together which makes the load heavier. Students need to
bear the extra load to go to school every day which will cause exhaustion to
the body from carrying the load of the bag. It depends on the student’s
behavior and how the students carry their bags.
