Recyclable Materials
Eco-Bags
1. Polypropylene (PP) Non-woven material. 100% made from Polypropylene (PP). The raw material is used for producing non woven fabric is PP granules that are made from petroleum. The granules can be coverted into small fibers, and then binding the fibers mechanically. At last, it becomes the cloth material by adhesive and thermal process called Spun-bonded.
Also we can offer polyester non woven bags. For further please feel free to contact us.
2. Polypropylene (PP) Woven material. Also 100% made from Polypropylene (PP). PP woven material firstly involves Cast extrusion of a wide sheet of PP which is cut into long trends which are then woven together to make a continuous sheet of woven material.
Only simple print work is managed using Flexographic presses or screen printing. Due to the rough surface of PP woven / PP Non woven material, high definition printing must first be printed onto BOPP or OPP, and then laminated (using extrusion coating) together with the PP woven / PP Non woven fabric.
if you want to know more about the chemical and physical properties of the material Polypropylene, please check the online encyclopedia - WIKIPEDIA. it gives you very detailed and accurated information.

3. Paper & Kraft Paper
Paper is used for writing upon, printing upon, for packaging and for bags. It is produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets.
Paper is a versatile material with many uses. Whilst the most common is for writing and printing upon; it is also widely used as a packaging material, in many cleaning products, in a number of industrial and construction processes, and occasionally as a food ingredient, particularly in Asian cultures.
Kraft paper is produced by the kraft process from wood pulp. It is strong and relatively coarse. Kraft paper is usually a brown colour but can be bleached to produce white paper. It is used for paper grocery bags, multiwall sacks, envelopes and other packaging.

5. Polyester
Polyester is an artificial man-made fiber. Polyesters are generally manufactured from petroleum from which the constituent acids and alcohols are derived. Dyeing can give desired colors of polyester fiber. Normal polyester fiber is long and smooth. Crimping it can give the fiber more bulk and texture and increase its insulation capabilities. Once the polyester fiber is ready it is used to make filament and spun yarns. The yarns can be blended with other fibers to make various blended fabrics.
Polyester VS Nylon
Polyester fabrics perform better than nylon for moisture management because polyester is more hydrophobic. Nylon threads will absorb more water than Polyester, water requires more heat energy to warm than does air, so nylon will feel colder when wet, and stay wet longer, and when saturated impede breathability.They're both tough, can be woven from very fine to very heavy fabrics, can be dyed, printed and coated to be very water resistant. Both are quick-drying, mildew resistant and melt at about the same melt point (480 F). They both degrade with extended exposure to the sun. UV inhibitors can mitigate this for both fabrics.
So what are the differences you might consider? For the same size, width, coating, etc. of fabric:
Polyester is often less expensive than Nylon.
Nylon is stronger than Polyester by about 10-15%.
Nylon is more abrasion resistance than Polyester and so is favored for outdoor luggage and sports applications.
Polyester is more resistant to stretching and shrinking than nylon, making nylon the preferred fiber for applications where stretch and shock resistance are required, such as in parachutes.
Polyester fibers are more non-hydrophilic (non-water loving) than Nylon fabrics and so are used for wicking and oisture control fabrics.
Polyester does retain odor longer than Nylon so hunting clothing tends to Nylon. Although both fabrics suffer from UV exposure over time, the dyes used to color or print Nylon fabrics fade more quickly than those used in Polyester. Swimsuits, boat covers, tarps, etc. are often made from Polyester for this reason.
Polyester fabrics can be recycled (usually into spun fleece) while Nylons are not currently recycled.
Where Polyester and Nylon fabrics diverge significantly is in their chemical behavior. They are chemical mirror images
of each other. Polyester favors acidic environments (pH<7.0), while Nylon favors alkaline environments (pH>7.0). Given
exposure to the wrong chemical environment, either fiber will deteriorate rapidly, especially at elevated temperatures.

6. Recycled PET (RPET)
RPET stands for recycled PET, the bottles that we are all familiar with used for water and soda. The recycle symbol #1. PET is Polyethylene terephthalate, a member of the polyester family, which most people don't realize. What has always been the case is that PET is the same chemistry as polyester. The difference is that a PET bottle is molded and polyester is a fiber. So in most respects PET and Polyester are synonymous.
