Product Description

Crystal clear laminated flap seal bags are a great choice for bulk mailings. LB49 is our 4 5/16" x 9 3/4" bag that is the perfect size for a #10 business size envelope and card. Easy to use and seal, these bags are made with 1.6 mil blended polypropylene for extra tensile strength and crystal clear clarity. Products such as crafts, socks, wrapping paper, and even tennis balls work well in this package. Stronger side seams prevent ripping or tearing, making this transparent sleeve an excellent mailer. The adhesive strip is on the bag flap and can be customized by adjusting the height. Simply fold the flap over as needed and seal for a secure fit.
