Bags meant for storage often find usage in homes. There are some bags that are of one time use and there are some that can be reused again. Those that can be reused are termed as resealable or reclosable bags. One such kind includes ziplock bags. These bags are meant for storing usually food and dairy products. Made of Polyvinyl Chloride, the bags are meant for storing deep freeze food items usually.
These bags are different from resealable bags in a way they are closed. The bags are closed with seals by pressing and opened with hands. In ziplock bags, the packets are resealed and opened by Zips that can be dragged on the edges of the bag. You may get many kinds of bags available in market that vary in different shapes and sizes. From square to rectangular they come in more shapes than one can think of. The sizes can be as small as the size of a computer mouse and as big as a computer screen. Small ones are used invariably in storing items like stamps; buttons, coins, toy parts etc. and large ones are used to store materials like clothes and electronic items.
Shielded bags are also reclosable bags that are used often in storing items like remote controls, batteries etc. These bags are sold with casings in market. They can be also used to store ornaments because the use of transparent bags will not serve the benefit of storing ornaments in shielded bags. They are used in storing high sensitive components that does not allow the material stored inside to decay.
Reclosable bags are basically meant for retaining the vacuum inside the bag so that moist, dust, dirt and insects are kept at bay. The zip in ziplock bags is made of plastic usually but can be made of other materials like wood too. Often the materials through which the zip is made is said to be light in weight. They are either equivalent to the bag’s weight or lighter than it.
These bags are great for storing purposes because they help in more ways than one. They help today and will continue to do so in future as they are hardly irreplaceable.
In order to create papers, there are some chemical pulping processes used. In these processes separations of cellulose fibers from lignin takes place. Lignin is first dissolved in liquor. The papers made through this process is also called wood free papers. The kinds of chemical pulping processes used in creating paper are sulphite and kraft processes. The kraft paper is the most used method. However there are other advantages to this method. It is used to create electricity which is produced by heat created through the chemical reaction with lignin. This electricity produced is used to run the generators. Also the method recovers the inorganic chemical reagents.
Kraft paper is also called sack kraft paper or sack paper. It is porous in nature and have high elasticity. The pulp reamed in the kraft process is stronger than sulphite processes. The main reason behind this strength is low content of lignin. Linens are hydrophobic and usually interferes with the cellulose fiber’s hydrogen bond. The paper produced through this process is darker. However through bleaching processes the paper can be made white.
Kraft papers have many uses to its credit. They are used to create paper folders which are used to keep all important documents and papers. They are used in producing envelopes, Multiwall sacks and grocery bags. For sandpaper the base paper is the kraft paper. Since it is cheap, the paper is also used in lining particle boards. Stationery boxes created from kraft papers are used avidly. It is a perfect way to keep all items in one place. The boxes are having silver holes on both sides that can be used for holding purposes. The stationery boxes are a perfect gift for housewarmings, birthdays, wedding anniversary and Christmas.
Why kraft papers are used in making stationery boxes and other so many areas is because of their varied quality and features. The prime quality being that it is strong and have high tensile strength. It has high tear resistance and is used invariably to create products that are of high strength and durability. The paper is highly absorbent in nature and has a good uniformity.
