UV MASTERBATCH SOLUTIONS FOR WOVENSACK
Need UV-protection for your Woven-sack products? We’ve got you covered! Our UV range is available for both Food Grade and Non-Food Grades, based on Hindered Amine Light (HAL). In general Plastic woven sack are sensitive to sunlight, it’s exposure to UV radiations causes degradation of plastic .
Our Plast UV masterbatch based on Hindered Amine Light Stabilizer (HALS) helps to extend durability of plastic products exposed to UV (Sun) radiation. This is the only product to sustainably decrease the reaction of degradation of plastic products which results in long life of the products. Plast UV are offered in food grade and non
– food grade applications. Our UV Masterbatches can be used in production of Cement Bag, pp fabric, Laminated Bag, Tarpaulin, Fertilizer Bag, PP bag etc.
▪ Technical Features :
• Synergistic combination of oligomeric high molecular weight HALS
• Protects plastics from Photo degradation and long term heat exposure
• Low volatility, low migration and good resistance to extraction
• Low gas fading and low pigment interaction
• Suitable for applications requiring indirect food contact compliance

TROUBLE SHOOTINTG GUIDE FOR WOVENSACK
PROBLEM POSSIBLE CAUSES
FILM PUNCTURE Hold up particle
GELES, HARD OR UNPLASTICIZED
PROFILE
DENIER
VARIATION
Improper back pressure. Improper temp gradient. Moister in master batch.
Extruder surging. Film thickness variation across width. Spacer thickness variation. Improper drive Performance.
TAPE BREAKAGE Excessive stretch ratio. Low orientation temp. Hold up particle in film. Very stiff film. Extruder surging
LOW TENACITY / HIGHER ELONGATION
Low stretch ratio. Too soft film. Low orientation temp
SOLUTIONS
Change screen pack. Check Row Material Moisture. Check heat stability of master batch.
Change temp. Profile. Use fine wire mesh. Reduce die lip opening. Reduce adaptor flow area. Change screw geometry. Pre-dry master batch.
Refer problem III in general extrusion processing. 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.
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.
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. Use anti fabrillation MB. 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.
