The Polypropylene Revolution
Gaia is a Polypropylene manufacturing company of customer-specific packaging and carrying with emphasis on state-of-the art packaging design and local services close to customer facilities. With a proFFduct portfolio that includes transit packaging, consumer packaging, displays and promotional packaging, customized protective packaging and industrial packaging, boasting a venerable cavalcade of clients, Gaia answers to each market requirement.
Polypropylene (PP) also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles, stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids. Gaia puts this multifunctional proficiency to use for a myriad of clients all around the globe.
Polypropylene itself is degradable due to its liability to chain degradation from exposure to heat and UV radiation, i.e sunlight. Degradation occurs through oxidation, it shows up as a network of fine cracks that become deeper and more severe with prolonged exposure. To further aid the biodegradation, microbial communities isolated from soil samples mixed with starch are capable of degrading polypropylene completely, making it simultaneously both recyclable as potentially highly degradable. Polypropylene is safe enough that it has even been reported to degrade while in human body as implantable mesh devices.
Due to the customizable nature of PP, the answer to that question depends on the specifications that go into producing the bag. Typically, a Polypropylene bag begins degrading when exposed to sunlight for extended periods of time. This time can be stretched or contracted through modifications in the resin during production. It can be made to last for years in direct sunlight, or it could be made such that it starts showing signs of degradation within weeks of UV exposure. However, if the bags are stored in a covered area, the bags will continue to be usable/reusable for extended periods of time.
PP bags are traditionally waterproof, so they do not weaken during rainstorms either/
Weaving is a method through which a sheet of polypropylene is cut into tape, as described in the Gaia Process, which is then warped and wefted into a fabric. This fabric is then cut and sealed in the shape of a bag that can be made to fit a myriad of sizes (further explained in question number X)
To accommodate the growing environment concerns the world over, polypropylene is the ideal choice, because of its ability to adapt to any specification in production as well as the fact that it is:
In simple terms, the difference is strictly in their function. A bag is, a flexible container with a single opening that has handles for easy packaging and usually for carrying lighter weights. A sack is usually described as a packaging solution for heavier weight objects. However, as far as the actual physical material is concerned, they are both the same thing. In the industry, they are recognized as different names for the same thing.
Polypropylene bags have a few different names:
Polypropylene bags are commonly used in the packaging industry to transport large sacks of different products for other industries such as, Salt, rice, coal, flour, sandbags, feed, seed, cement, sugar, fertilizer, firewood and certain chemicals.
However, Gaia bags can also be tailored for usage in commercial stores, shopping marts, carrying bags, etc.
Woven polypropylene is a great fabric to print on. It can accommodate practically any design from simple single color printing, to complex three toned bleedless prints. You can even seamlessly print digital artworks with 100% print coverage.
Glossary of woven polypropylene bags
Definitions of Woven Polypropylene Bag
Polypropylene – A type of polymer used in producing monofilament and multifilament yarns and threads.
Yarn / Tape – Extruded PP sheet, slit and stretched in annealing ovens to form a woven fabric.
Warp – Yarn or tape in a fabric, oriented perpendicular to the Weft yarn during weaving. This would go from top to bottom in the body fabric.
Weft – Yarn or tape in a fabric, orientated perpendicular to the Warp yarn during weaving. This would go from left to right in the body fabric.
Woven – Combined with numerous yarns/tapes in two directions, warp and weft, to form fabric.
Breathable Fabric / Bags – Uncoated or non-laminated fabric / bags.
Circular Woven Bag – Also called a tubular bag, it is made from fabric woven on a circular loom, which is then cut to lengths to meet customer satisfactions. This technique eliminates visible stitching.
Coated Fabric / Bags – Fabric or bag which is coated / laminated with Polypropylene (PP) to prevent moisture intrusion or sifting of the contents. Also called Non-breathable or Laminated fabric / bags.
Bag Size – width and length measured from the Top Seam to the Bottom Seam.
Printing Design – A drawing supplied by the plant for the prospective customer’s review and approval, prior to production, in order to assure compliance with the customer’s needs and expectations.
UV Stabilized – A feature of a unit of woven polypropylene bag that provides protection from prolonged exposure to the sun’s degrading UV rays. A pigment is added to the resin prior to extrusion of the yarns to provide this protection.
