2. Packtech:
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.

3. 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.

4. The technical textile products covered under Packtech
are
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.

5. 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:
•Cement
•Fertilizers
•Chemicals
•Food Grains
•Cattle Feed
•Salt
•Sugar
•Polymers
•Sacks - Export
•Others

6. 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:
• Higher Strength
•Light Weight
•Minimal Seepage
•Moisture Proof
•Long Lasting (Durable)
•Cheaper (as it can be reused)

7. 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).

8. There are three types of FIBC bags:
•Panel Type
•Circular woven
•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)

9. Uses of FIBC:
1. It is used in bulk packaging of
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

10. Leno bag
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 Master
batch.
Advantages of a Leno Bag:
 Excellent mechanical properties
 Superior aesthetics
 Chemically Inert
 Ease in handling & storage
 Reuse & recyclable
 Cost Effective
 Suitable for dry skin vegetables (Potato, Onion,
Garlic etc.)
 Suitable for cold storage

11. Wrapping Fabric:
Wrapping fabric is made out of HDPE/PP, cotton canvas, etc.
Unlaminated PP/HDPE Woven Fabric ismainly 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 formanufacturing
bags too.

12. 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 inlarger 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.

13. 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.
Jute sack
Different categories of sacking
are:-
• A-Twill
• B-Twill
• L-Twill
• D.W. Flour
• D.W. Salt
• D. W. Nitrates
• Heavy Cees
• Light Cees
• Sydney Woolpacks
• Australian Woolpacks
• Australian Cornsacks
• New Zealand Cornsacks
• New Zealand Woolpacks
• Fine Twill Cloth
• Cement Bags

14. 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 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.

15. 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
