pla biodegradable Portable Standup Bags
Portable stand up bags is a kind of bag which has a side gusset and vest handle. Seriously , it is same as bread packing bags. Color of this bag is natural color. Thickness: 60 microns or 40 microns, 80 microns can also be ok.
At present, the bags of packing gifts are more popular , but the plastic material is not good to the environment. While this kind of portable stand up bags is a good way to solve this problem. Bags can be print, you can print one or two color on the bags and make it more elegancy.
Materials pla materials, 100% biodegradable, can be degraded into carbon dioxide and water. In the case of industrial composition, in natural environment, the degraded circle will be longer , the shelf life is about 12-24 months.

Are you manufacture or trade company?
-We are manufacturer that also owes exports rights.
Price: How can I get a good price?
-Price related to the different size, thickness, whether print or not... etc, pls send us your request about the product you need so that we would calculated price for you
How could you prove that your products are PLA biodegradable?
-We have testing reports from professional institute of our products which it’s the most directly way to prove it. and we will also provide other certificates to you.
Can I customized print or the bags' size?
-Yes, of course. Size and print can be customized.
How much do I need to order? (What are the minimum order estimates?)
That depends on the type of product and whether or not it is being printed.
The figures below are the average base prices for custom orders, meaning it is the minimum dollars that you should expect to spend on a give bag or box type. Actual quantities and costs will depend on the size of the bag and the complexity of the project.
Crystal Clear Bags
Unprinted typically start at $250 to $300
Printed 1-2 colors typically start at $500-$600
Printed 3+ colors typically start at $700+
Stand Up Zipper Pouches
Unprinted typically start at $700-800
Printed 1-2 colors typically start at $1000-$1250
Printed 3+ colors typically start at $1400+
A brief history of plastics
A typical bakelite electric power adapter from the 1950s or 1960s.
Photo: Bakelite, an important early thermosetting plastic, was widely used to make telephones, lamp fittings, and other electrical equipment during the first half of the 20th century because it's tough, hard, heatproof, and an excellent insulator. If you see a phone in this characteristic brownish-black color, with a dull finish, it's probably made of Bakelite (although it's worth noting that Bakelite also came in other colors). This power adapter from England dates from the early 1960s.
Ancient people start using plastics (natural materials like rubber, animal horn, and tortoiseshell are made from polymers).
1838: Injection molding is developed for diecast metal products (a technology that will later revolutionize plastic-making).
1839: Charles Goodyear develops vulcanized (heat and sulfur treated) rubber—an example of a tough, durable cross-linked polymer.
1855: Georges Audemars, a Swiss chemist, makes the first synthetic plastic silk fibers using mulberry bark and rubber gum.
1856: Alexander Parkes develops the first artificial plastic, Parkesine, by making nitrocellulose from cellulose and nitric acid.
1875: Alfred Nobel invents gelignite, a plastic explosive also based on nitrocellulose.
1885: George Eastman (of Kodak camera fame) revolutionizes photography by making plastic photographic film from cellulose.
1894: Viscose, the first commercially successful artificial silk (a form of rayon), is produced by Charles Cross, Edward Bevan, and Clayton Beadle.
1907: Belgian-born chemist Leo Baekeland makes the first fully synthetic thermosetting plastic, Bakelite, from phenol and formaldehyde. He experiments with injection molding around the same time.
1920: American John Wesley Hyatt develops the first injection molding machine for plastics.
1930: American chemist Wallace Carothers and his team at DuPont accidentally discover a weird new material. It soon becomes nylon, a wildly successful plastic that revolutionizes textile manufacture.
1930: Transparent, "Scotch" sticky tape is invented by Richard G. Drew of 3M.
1930s: German chemist Eduard Simon accidentally makes polystyrene, initially called styrol oxide and, later, metastyrol.
1938: Roy Plunkett of DuPont accidentally discovers PTFE (Teflon).
1942: Harry Coover of Eastman Kodak invents plastic superglue (methyl cyanoacrylate).
1949: Lycra (a type of polyurethane) is invented by DuPont.
1949: American Bill Tritt builds the Glasspar G2, the first production sports car with a body made entirely from fiberglass (a plastic composite).
1953: Karl Ziegler develops aluminum catalysts for speeding up polymerization.
1954: Giulio Natta develops polypropylene, first made by Italian chemical company, Montecatini.
1955: Building on earlier work by Karl Ziegler, Natta perfects Ziegler-Natta catalysts.
1954: Dow Corning invents expanded polystyrene.
1958: George de Mestral files a patent for VELCRO®, the reusable plastic hook-and-loop fastener.
1966: Stephanie Kwolek and Paul Morgan of DuPont are granted a patent for Kevlar®, a super-tough plastic similar to nylon. It's commercially introduced in 1971. Also in 1966, another DuPont chemist, Wilfred Sweeny, is granted a patent for a chemically similar nylon-relative called Nomex®, a revolutionary fireproof material.
1982: The Jarvik 7, a complete artificial heart, made from plastic polyurethane, is first implanted in a human.
1988: Australia becomes the first country to issue high-security plastic banknotes.
1990s: The first modern 3D-printers are developed. They can make realistic models of objects by squirting out layers of hot ABS (acrylonitrile butadiene styrene) plastic.
1997: Captain Charles Moore discovers the Great Pacific Garbage Patch.
1998: Smart cars made from composites enter production.
2001: Scott White, Nancy Sottos, and collaborators at the University of Illinois at Urbana-Champaign develop remarkable self-healing materials from plastics.
2002: British inventor Richard Palmer files a patent for a revolutionary energy-absorbing plastic, which he calls D3O, that can soak up the force from impacts.
2016: Japanese scientists report the discovery of bacteria that can eat plastic bottles.
