It is not simply a PE bag. The advantage of this synthetic material is that there are no pores, and if it is pure PE, the bag will have pores even if it is thick, and it will leak out over time.
2. High temperature cooking bag. This is a better kind of bag than the vacuum packaging bag, of course, the cost price is also higher. This kind of bag can be vacuum-packed and can be used for high-temperature cooking. Its quality is reliable and it is mostly used in the food industry.
