What are the plastic packing bags used in disposable medical products, and are they made of composite or single deck?
A one-time affirmation is a single layer, ah, this depends on what specific field, and the general is single.
As if most of the PP do, but also PE and PVC material, PP more crisp, hard texture, the price is slightly expensive, good environmental performance, PE and PVC transparency higher, smooth and soft texture, the price is relatively low.
