Starlinger makes AD*STAR® sacks whereas AD ProTex is made on Windmöller & Hölscher machinery. Both companies manufacture similar sacks, which are block bottom with no adhesives, from coated polypropylene fabric with Nano Perforation for breathing while filling is done through funnel or spouts.

Open mouth bags are made from polypropylene fabric, which are closed on one side of the tube by sewing.

Although no formal testing has taken place but if stored in room temperature without sunlight these bags may last for 2 - 3 years, however laminated bags may last for a year.

Filled sacks are dropped from 2.5 meters flat on the ground to check burstage.

The lamination on AdStar sack and PE liner inside Open mouth bag has shown better water resistance compared to Paper Bags.

Due to less sack weight and zero burstage; PP bags are cheaper than Kraft Paper bags.

Yes, due to high calorific content these PP bags can either be recycled or mixed with coal to generate power in cement industry.

Depending on the quantity and transit time but as a general rule of thumb first batch should reach destination port in 45 – 60 days.

We can ship all over the world.

All vendors prefer L/C term as both parties are safe, but in special cases can work on CAD and companies with good credit / guarantees may get upto 30 days credit term.

Yes we can and we can also make open mouth block bottom

There are generally 4 types of known Jumbo bags. Following are the types and usages of FIBC bags:

Jumbo A (Regular FIBC)

Regular Jumbo Bags are manufactured from regular PP fabric by adopting a special technique to keep the fabric break down. Jumbo Bags are cost effective solution for bulk packing. They are mainly used for chemicals, fertilizers, fiberglass, food products, seeds, peanuts, starch, grains, mining, construction, pigments, plastics, and other agricultural products.

(ii) Jumbo B (Anti-static Bag)

The polypropylene fabric is woven with special conductive tape. This provides continuous and effective collection of charges through all points. Conductive straps are used with ground tabs to ensure grounding. Voltage less than 6 kv as per standard IEC 61340 4 – 4. Electrostatic charges are conducted to the ground via conductive tape, eliminating static discharges from the bags when grounded. 

It is mainly used for chemicals, fertilizers, fiberglass, food products, seeds, peanuts, starch, grains, mining, construction, pigments, plastics, and other agricultural products.

(iii) Jumbo C (Earth Conductive Bag)

These bags are made from fine conductive threads. An antistatic bag, or conductive bag, is a shipping bag for electronic devices, which can be affected by electrostatic.

These plastic bags normally and have a distinctive color according to its properties:

  • Check-Image Silver for metalized PET film and other similar plastics.
  • Check-Image Pink or black for polyethylene.

* The polyethylene model can also be made as foam or bubble wrap, either as sheets or bags.

To create the anti-static effect, the black bags or silver bags are slightly conductive, forming what is known as a Faraday Cage around the item to be protected avoiding any discharges from being deposited onto the protected devices as the bags are handled.

(iv) Jumbo D (Dissipative Bag)

It is a special type of bag that doesn’t store static electricity. Static is deadly to electronics. Dissipative properties should be tested as per standard IEC / ISO 61340- 4 – These bags are used to transport flammable powders, when flammable or gas present around the bag.
