Five-Ply Bag Closing Thread in 12S/5 Spun Polyester

MH 12S/5 Spun Polyester Bag Closing Thread is a 100% spun polyester industrial sewing thread built from five plies twisted in the S direction at Ne 12 cotton count.

MH 12S/5 Spun Polyester Bag Closing Thread is produced in raw white as standard and dyed to customer colour references for line or grade identification. It is used to close woven polypropylene sacks, kraft paper sacks and multi-wall paper bags in grain, feed, fertiliser, sugar and cement packing, and runs on single-needle chain-stitch closing heads as well as inline closing stations mounted over a conveyor. Alternative cotton counts and ply combinations are spun and twisted to order for buyers standardising a thread range across several bag types.

Wichtige Verkaufspunkte

• Balanced five-ply construction: The five-ply build of MH 12S/5 spun polyester bag closing thread adds real seam strength over four-ply threads while staying finer than six-ply yarns, so heavier sacks can be closed without increasing needle drag.
• Uniform S twist: Consistent S-direction twist keeps the plies of this bag closing thread closed as it feeds through the tensioner and needle, which reduces fraying, skipped stitches and thread breaks on continuous closing lines.
• Spun polyester durability: Spun polyester gives the thread high abrasion resistance and stability against moisture and mild acids, so closed seams survive stacking, hook handling and outdoor storage of filled bags.
• Low shrinkage and colour fastness: The thread is engineered for low shrinkage and colour-fast performance in industrial packaging, keeping seam tension and thread appearance stable from the packing line to the buyer's warehouse.
• Colour and private-label customisation: MH dyes the bag closing thread to customer colour references and applies private-label cone and carton marking, which lets packers colour-code grades or brand the thread for resale.
• Wholesale and OEM supply: MH spins, twists and winds this bag closing thread in-house for wholesale and OEM programmes, supporting repeat bulk supply to bag manufacturers and packaging exporters.
