LENO BAG
Leno weave (also called gauze weave or cross weave) is a weave in which two warp yarns of Polypropylene are woven around the weft yarns to provide a strong & sheer fabric. The standard warp yarn is paired with a skeleton or ‘doup’ yarn; these twisted warp yarns grip tightly to the weft which causes the durability of the fabric. Leno weave produces an open fabric with almost no yarn slippage or misplacement of threads. Leno bags are made from such fabric whose primary characteristics are good aeration & strength. They are available in various sizes ranging from 5 to 50kgs and it’s used for packing & preserving material for vegetables such as potato, onion, ginger, garlic, cabbage , peas , etc & fruits such as pineapple, citrus fruits, raw mango, coconut etc. The Leno bags are made on circular/ Flat weaving leno looms having widths ranging between 30cm to 200cm. Generally denier of 600-650 is preferred, the length varies as per the customer’s requirements. Mouth sewing will be seem or overlocked / chain stitching . Leno bags are availabled in wide colours but most preferred are Red, orange, Yellow, Green & Blue . It’s easy to do labelling , lamination & printing.

Trouble Shooting Guide
| PROBLEM | POSSIBLE CAUSES | SOLUTIONS |
|---|---|---|
| FILM PUNCTURE | Hold up particle | Change screen pack. Check Raw Material Moisture. Check heat stability of master batch. |
| GELS, HARD OR UNPLASTICIZED PROFILE | Improper back pressure. Improper temp gradient. Moister in master batch | Change temp. Profile. Use fine wire mesh. Reduce die lip opening. Reduce adaptor flow area. Change screw geometry. Pre-dry master batch. |
| DENIER VARIATION | Extruder surging. Film thickness variation across width. Spacer thickness variation. Improper drive Performance | Reduce throughput rate. Increase die volume. Adjust die lip. Check uniformity of die temp. Check spacer thickness. Use carbon steel blade. Check drive performance. Check temperature of orientation unit across width. Check flow velocity of hot air across width. |
| TAPE BREAKAGE | Improper stretch ratio. Low orientation temp. Hold up particle in film. Very stiff film. Extruder surging | Increase stretch ratio. Increase orientation temperature. Refer problem of film puncture and gels, hard or unplasticized particles. Increase distance between die opening and water levels in tank. |
| LOW TENACITY / HIGHER ELONGATION | Low stretch ratio. Too soft film. Low orientation temp | Increase stretch ratio. Increase distance between die opening and water level in quenching tank. Increase orientation temp |
| TAPE FABILATION | Tape too stiff Scratches on tape moving path. | Polish tape moving path. Use wear resistance material items. |
| SHRINKAGE IN FABRIC/ CURVED TAPE | Residual stress in tape | Check annealing system. Increase annealing temp. Check cooling efficiency of roller. |
| FIBRILLATION / LONGITUDINAL SPLITTING OF TAPES | Contaminated die lip | Adjust die gap & clean die if needed |
| Non uniform film thickness. Blunt cutting blades on spacer rod | Replace damaged cutting blades | |
| Wrinkles in films/ tapes | Adjust temperature during film manufaturing for wrinkles | |
| Serration on hot plate Lower hot plate temperature | Increase hot plate / oven temperature | |
| Too high stretch ratio | Reduce stretch ratio | |
| Higher winding tension | Adjust winding tension and check traverse guide of winders. |
