The Serious Source for Safety: Sizing Charts
Serged Seams
A serged seam joins two pieces of material with a thread that interlocks. This is an economical stitching method for general applications. This stitching method is generally not used for chemical protective clothing. It is more commonly found on limited use clothing where dry particles are of a concern.
Sewn & Bound Seams
A sewn and bound seam joins two pieces of material with an overlay of similar material and is chain stitched through all of the layers for a clean finished edge. This proviedes increased holdout of liquids and dry particulates.
Heat Sealed Seams
A heat sealed seam is sewn and then sealed with a heat activated tape. This method provides liquid proof seams, and is especially useful for Level A and B chemical protective clothing.
Heat Sealed Seams Plus
This is the strongest seam that Lakeland offers. The seam is sewn and then heat sealed on the outside and inside to offer the highest strength and chemical resistance.
