Types of courier plastic bags

• A polyethylene bag without a pocket on the outside is smooth, white. It can be marked with company markings. Inside, it is insulated with black material. The closure of the bag is fixed with adhesive tape.

• Some models of courier plastic bags have a field with a personal barcode of the product, a pocket and a fastener on the adhesive tape.
• Courier plastic bag with knock-out handles is more convenient for the courier to deliver the parcel.

Courier plastic bags differ in size. Some manufacturers make them in non-standard length and width ratios. A few examples of sizes of courier plastic bags:

• Small package - 150 x 210, 190 x 240 mm.
• Medium package - 220 x 260, 240 x 320 mm.
• Large package - 305 x 405, 355 x 508, 380 x 520 mm.

In order to choose the right courier plastic bag, measure the length and width of the things that need to be placed in it. It is necessary to leave a reserve for volume. Note that the thickness of the parcel should not be too thick, because then you need extra space in the package. If things will be much smaller than the package, it is acceptable. However, it is important that the material tension of the courier plastic bag is not too strong. This reduces its strength.
