Guide to Woven Polypropylene Packaging
Guide to Woven Polypropylene Packaging
It's best to split this into categories to get a better understanding:
1. Woven Fabric
Woven/weaving is a method where threads or tapes and reel of woven in two directions which is known as the Warp and Weft. This is what for the Woven fabric for various uses across difference industries.
In woven plastic industry, with a plastic in film which comes in carious thickness is drawn into filaments, woven into fabric material and sheeting on rolls or cloth made to measure.
The end product could typically become a Tarpaulin or Woven Sacks, Bulk Backs. Container packaging bags, Builders Tone Bags and also used as Geotextiles, The Fabric can also be coated in various colours with logo, used with eyelets and safety warnings signs can be applied during production or in-house stock convertion for small runs.
2. Poly Plastic Industry & Textiles Industry
The source of the Poly Plastic film in a fibre belong to the poly plastic industry;
The weaving process and filament of the plastic is generally from the Textiles Industry. Most of raw material is manufactured in China, India, Pakistan, Vietnam and Far Asian countries.
Woven is fabric does tend to frays on the edges, however many methods can be used to prevent and reduce fraying, such as the use of hemming and pinking shears.
3. Woven Polypropylene
Polypropylene, is also known as PP or WPP for short and is one kind of thermoplastic resin material that is produced by the polymerization of propylene.
What gives Woven Sacks their strength where strips/threads of woven polypropylene is weaving in two directions (warp and weft) which creates a light, durable, strong and heavy duty fabric material.
Why Woven Polypropylene Sacks are used widely used in the Packaging IndustryHigh Melt Index with low Density
• 100% reusable and durable
• Easy to clean and anti bacterial
• Light in weight with lowest density
• breathable or water proof with a laminated film
• Easy to produce, assembly and an economic material
• Excellent resistance to stress and high resistant to cracking
• High operational temperatures with a melting point of 167°C
• Resistant to most alkalis and acid, organic solvents, degreasing agents & none staining
Different names of woven polypropylene bags
woven polypropylene bags, woven polypropylene sacks
Bags or sacks is appropriate to describe something in a wide range of packaging types.
A bag is, a flexible container with a single opening.
A sack is, a bag made of paper or plastic for holding.
Sack is just one type of Bag, especially applying to the packaging industry. In fact, most countries use bags more frequently than sacks. There will be differences but little, so as far as we know, woven polypropylene bags/woven polypropylene sacks.
Short names of woven polypropylene bags/sacks
• pp bags/sacks
• wpp bags/sacks
• woven bags/sacks
• woven pp bags/sacks
• woven poly bags/sacks
Use names of woven polypropylene bags/sacks
• courier mailing bags, post office sacks
• rice bags
• coal bags
• flour bags
• feed bags
• seed bags
• cement bags
• fertilizer bags
• firewood bags
• chemical bags
The fact is different names used in different countries and regions across the globe.
Properties of Woven Polypropylene Sacks
The properties of woven polypropylene bags come from two aspects:
1. Properties of polypropylene
2. Properties of woven method
Polypropylene has qualities of rot/flame/chemical resistance, and woven method means strong yet breath. Combining together with other factors, we got 9 facts of woven polypropylene bags.
· Woven Polypropylene Bags are reusable.
· Woven Polypropylene Bags don’t degrade when wet.
· Woven Polypropylene Bags are naturally resistant to tearing.
· Woven Polypropylene Bags can be printed on one side or both sides.
· Woven Polypropylene Bags allow the contents to breath until air dried.
· Woven Polypropylene Bags have better burst strength than plastic bags.
· Woven Polypropylene Bags can be laminated as the vapor and moisture barrier.
· Woven Polypropylene Bags can be partially transparent for outstanding presentation.
· Woven Polypropylene Bags can be side gusseted to accommodate bulky items easily.
Applications of Woven polypropylene Sacks
Agricultural product packaging
Woven bags are largely used in storing and transporting agricultural products such as aquatic products, feeds, fruits, vegetables, etc. PP woven bags used in the agricultural industry typically include feed PP woven bags, chemical PP woven bags, fertilizer PP woven bags, vegetable woven bags and fruit mesh bags.
PP woven bags are increasingly used to pack food. Common food woven bags include rice PP woven bags, flour PP woven bags, maize woven bags, etc.
PP woven fabrics are extensively used in the construction of irrigation works, roads, railways, ports, mines, buildings, and more. Having the functions of filtering, draining, isolation and anti-seepage, PP woven fabrics are one of the most popular geosynthetics.
Tourism and transport
Temporary tents, sunshades, and various travel bags can be made by PP woven fabrics. In addition, plastic woven fabrics can also be used as fences and screens during construction.
PP woven bags are almost used by everyone, whether workers, farmers, or cargo agents etc. You can find plastic woven products (such as shopping bags, logistics bags etc.) in stores, warehouses and houses, nearly everywhere.
Flood control products
Woven bags play an important role in reducing or preventing the detrimental effects of flood waters. They are widely used in the construction of dams, river banks, roads and railways. Woven polypropylene sandbags are widely used all over the world.
Special woven bags, Charity Clothes Sacks, Shoe Sacks, Botany Woven Sacks
Special woven bags are used to serve some special purposes. For example, UV resistant woven bags have UV protection and anti-aging function, allowing them a longer lifespan in the sunlight. Woven polypropylene tube with UV protection can be used for earthbag geotextile for buildings and construction.
Is woven polypropylene an eco-friendly material?
Yes, it’s an eco-friendly fabric, therefore it can be melted down, recycled and made into other products. Besides, they last long enough and can be used many times to reduce demand from Single-Use and disposable products.
Woven polypropylene bag can last for many years.
Can woven polypropylene bags printable?
Yes indeed, Woven polypropylene is a great fabric to print on. You can choose normal easy printing such as simple brand text and image with three colorus, also full colour printing with Bopp lamination.
Bopp laminated woven polypropylene bags is best suited to graphic and digitally created art work. Perfect for 100% print coverage with no limit to creativity.
