Generally speaking, most laminated bags tend to use the following three substrates. And, no matter what type of substrate you use, it only can be seen on the inside of the bag. In other words, you can not see the substrate you use from the outside of the bags.

●Woven PP: The PP strips are woven together, then bonded with the lamination layer. This material is sturdy, so the pp woven laminated bag can be used for producing sand bags, tarps, and other industrial uses. However, this material wrinkles after 6-8 months.

●NWPP: NWPP refers to the non-woven PP. The layer of non-woven lamination gives non woven laminated bag a strong, puncture-resistant top layer for a smooth great looking bag. Therefore, it could be the ideal option for non woven grocery bags and non woven promotional bags for any business.

●Recycled PET (rPET): The raw material of recycled PET (rPET) is shredded water bottles. The shredded water bottles are spun into a substrate fabric to create recycled reusable bags. Since the lamination sheeting is not recycled, the final product contains about 85% post-consumer waste. And, rpet laminated bag is the perfect flag in eco-friendly bags, which can confirm your commitment to the environment.
