(a) form an elongated rectangular band made of a plastic film material;
(b) fold the opposite long edges of the strap towards the middle to form a pair of side wings.
There is a gap between the inner edges of the pair of side wings to expose the central region of the strap.
Strap Method includes:
(a) forming an elongated flat-tube made of a plastic film material;
(b) Longitudinally cutting the tube to form a pair of wings of an upper layer material of the flat tube;
(c) a middle region of the lower layer material is exposed in the gap between the pair of side wings.
In any case, the method further includes:
(i) selectively applying an adhesive layer and an ink layer suitable for forming a tamper-resistant seal to the middle region;
(ii) cutting the tape from the middle of the middle region to form an elongated folded straps;
(iii) Cut the folded straps laterally at equal intervals to form a single folded material portion. These parts form a bag, such as by heat-sealing the cutting edges.
Forming a Tamper-proof Safety Bag Method Includes The Following Steps:
(a) forming an elongated rectangular strap made of a plastic film material;
(b) folding the opposite long edges of the strap toward the middle to form a pair of side wings. There is a gap between the inner edges of the pair of side wings to expose the central region of the tape;
(c) selectively applying an adhesive layer and an ink layer to the central region that is suitable for forming a tamper-resistant seal;
(d)cut the strap from the middle of the middle area to form a pair of elongated folded straps.
