Packtech | Textile Packaging Material | Advantages and Uses of Textile Packaging Material

To ensure scratch free and safe handling of sensitive articles Textile partitioned boxes/packages are an ideal option. These boxes/packages are very useful in Automotive industry for transportation and handling of sensitive components like lamp assemblies, fenders etc. Packaging material is one of the important branch of technical textile. We can define packaging as like below.

Packaging = (Functions / Costs) * Service

Savings are in the total logistic chain not in the packaging. Better protection higher density better ergonomics.

Packtech includes several flexible packing material made of textile used for packing various goods for industrial, agricultural, consumer and other goods. It ranges from polymer based bags used for industrial packing to jute based sacks used for packaging food grains and packaging used for tea. This packaging (excluding jute) is also referred to as flexible packaging materials.

The technical textile products covered under Packtech are as give below:
  1. Polyolefin Woven Sacks (excluding FIBC)
  2. FIBC
  3. Leno bags
  4. Wrapping fabric
  5. Jute Hessian and Sacks (including Food grade jute bags)
  6. Tea-bags (filter paper)
  7. Soft luggage products (TT component)
Woven sacks (excluding FIBC) account for around 50% of the technical textiles consumption under Packtech followed by Jute hessian and sacks (including Food grade jute bags) with around 30% share. FIBC and wrapping fabrics account for around 20% of the total usage. Usage of technical textiles in soft luggage products, leno bags and tea-bags is less than 5% of the total usage in Packtech.

A short description of packaging materials are highlighted below:

Polyolefin Woven Sacks (excluding FIBC):
Polyolefin (HDPE/PP) woven sacks are versatile packing materials used extensively in the packing of cement, fertilizers, thermo plastic raw materials, food grains, sugar etc. The list of user-industries where they are used is:
  1. Cement
  2. Fertilizers

Polyolefin (HDPE/PP) woven sacks

PP/HDPE printed sandwich bags are made by sandwiching PP and HDPE. They have a very good appearance and are used for packaging costlier products like pesticides, seeds, wheat flour, high-end chemicals, etc. They may also be used for secondary packaging of smaller 1kg bags.

Advantages of Polyolefin Woven Sacks Bags:
The various advantages that HDPE/PP bags have conventional packing materials are:
  1. Higher Strength
  2. Light Weight
  3. Minimal Seepage
  4. Moisture Proof
  5. Long Lasting (Durable)
  6. Cheaper (as it can be reused)
Flexible Intermediate Bulk Containers (FIBC):
Flexible Intermediate Bulk Containers (FIBC), popularly known as ―Jumbo Bags, is similar to the HDPE/PP bags but that of a larger size. FIBC‘s are one of the most cost effective and ideal types of packaging for shipping and storing dry bulk products. They can be produced from either tubular or flat polypropylene (PP) woven fabrics. These fabrics can be coated or uncoated and vary in terms of weights depending upon the requirements of the Safe Working Load (SWL), or Safety Factor (SF).
Jumbo Bag
There are three types of FIBC bags:
  1. Panel Type
  2. Circular woven
  3. Baffle type (Square bags)
These bags have capacities ranging from 500-4000 kgs. The weight of fabric varies from 180-275 gsm. FIBCs can vary from 900 gms to 3 kgs in weight depending upon the bag properties and weight to be carried.

Advantages of FIBC:
  1. Low cost of material handling from the manufacturer to the end user, inclusive of wastage of material
  2. Easy filling and discharge
  3. Savings in loading/unloading time due to ease of handling
  4. Low weight packing for transport
  5. Built in safety factor of at least 5:1 on nominal load
  6. Transportation of empty FIBCs is cheap and space saving
  7. No requirement of pallets when compared to small bags – self supporting
  8. Good chemical and organic resistance
  9. Eco-friendly, since product is recyclable
  10. Can be used for storage in open air (if UV stabilised)
Uses of FIBC:
It is used in bulk packaging of
  1. Polymers, such as PET and PVC
  2. Petrochemicals, such as DMT, PTA and polyester chips
  3. Minerals, such as bentonite, alumina, ebonite, magnesite, mineral ores like nickel
  4. Agro-products, such as wheat, rice, starch, lactose and sugar
  5. Chemicals, such as carbon black, dyes and intermediates and fertilisers
  6. Oil cakes (powder form)
  7. Detergents
  8. Oat meal
  9. Clay, mica and feldspar
  10. Cement
  11. Pharmaceuticals
  12. Fish meal
Leno Bags:
Leno bags are excellent for packing & preserving vegetables like potato, onion, ginger, garlic, cabbage etc. and fruits like pineapple, citrus fruits, raw mango, coconut etc. The Leno Bag is made of netted fabric of virgin Polypropylene (PP) with color Masterbatch.

Advantages of a Leno Bag:
  1. Superior aesthetics
  2. Excellent mechanical properties
  3. Chemically Inert
  4. Ease in handling & storage
  5. Reuse & recyclable
  6. Cost Effective
  7. Suitable for dry skin vegetables (Potato, Onion, Garlic etc.)
  8. Suitable for cold storage 
Wrapping Fabric:
Wrapping fabric is made out of HDPE/PP, cotton canvas, etc. Unlaminated PP/HDPE Woven Fabric is mainly used for wrapping of paper rolls, paper bundles, steel coils, tyres, yarn cones etc. Wrapping fabric weighs 50 to 200 gsm and its size varies from 20 to 210 cms. The fabric is generally packed in roll form and can be run on automatic cutting and stitching machines. Clear Woven Sheets (Natural Woven Laminated Sheets) are used for packing of used clothes etc.

Uses of Wrapping Fabric:
These fabrics are widely used in industries such as paper bundles, wrapping of paper rolls, steel coils, yarn cones, tyres etc. These fabrics can be utilized with automatic cutting & stitching machines for manufacturing bags too.

Jute Hessian and Sacks:
Jute Hessian:
Jute Hessian also termed as Burlap is a finer quality jute fabric that has been long used as the most preferred packaging material for all kinds of goods. Hessian is used for bags and many other coarse fabric uses, such as wrappers, wall coverings, etc. Presently, shopping bags are being made out of hessian fabrics. It is also used in the upholstery and home furniture. Also available in "dyed" or "bleached" form and treated with vegetable oil, Burlap meets the latest international standards for food safety.

Jute Sacks:
A range of heavy jute fabrics either in plain or twill weaves manufactured by using coarse jute fibre in larger percentage than used for manufacturing tarpaulin, hessian or such light fabrics. Sacking refers to the coarser and heavier cloth, used primarily for sacks for packing materials, which do not need special protection, but has higher weight. Jute bagging material is in demand because of the openness of the weave, which allows air to circulate while protecting the contents. 

Jute sack
Sacking bags, specifically used for the purpose of storing agro-based products, are known as Hydro carbon free bags that have been treated with vegetable oils to destroy the harmful effect of hydrocarbons. Thus sacking bags have great demand not just in the cement industry but also in the agro-based industries.

Different categories of sacking are:-

  1. A-Twill
  2. B-Twill
  3. L-Twill
  4. D.W. Flour
  5. D.W. Salt
  6. D. W. Nitrates
  7. Heavy Cees
  8. Light Cees
  9. Sydney Woolpacks
  10. Australian Woolpacks
  11. Australian Cornsacks
  12. New Zealand Cornsacks
  13. New Zealand Woolpacks
  14. Fine Twill Cloth
  15. Cement Bags
The difference between hessian and sacking is in the quality of the cloth and the jute used for its production, the difference being primarily one of fineness, the former being made of finer grade jute, the latter of coarser qualities. Hessian can be available in cloth lengths while the mills usually convert sacking cloth into bags and sacks.

Tea Bags:
Tea bags are sold by organised tea producers to the high-end consumers. Tea bags consist of a filter paper pouch with a thread, which holds the tea powder and a tag. The tea bag is dipped in hot water / milk to produce the beverage. 

Tea bag
Tea bag filter paper is made with a blend of wood and vegetable fibers. The vegetable fiber is bleached pulp abaca hemp, a small plantation tree grown for the fiber, mostly in the Philippines and Colombia.

Heat-sealed tea bag paper usually has a heat-sealable thermoplastic such as PVC or polypropylene, as a component fiber (100% non-woven technical textile) on inner side of the teabag surface. The filter paper used for making tea-bags is a 12-17 GSM non-woven material. The heat-sealing type tea-bag paper is of 16.5 to 17 GSM approx while the non-heat sealed tea-bag paper is around 12 – 13 GSM.

Soft Luggage:
The luggage industry is classified into hard and soft luggage. Hard luggage are mainly the large travel bags made from moudled plastic. Soft luggage is made out of woven fabrics like nylon and polyester. It comprises of uprights, totes, duffle and sky bags which can be with or without wheels and handles. The soft luggage today is becoming very popular due to the ease of carry as it is light and flexible. It includes handbags, military backpacks, athletic backpacks, wallets, briefcases and other soft sided luggage items.
