When you buy items on sale in bulk, vacuum sealing them and storing them in the freezer will prevent quality degradation and allow you to use them without waste. High quality, thick, and durable. Works even without a dedicated machine! Pleasant to the touch and worry-free from odor leakage. These are general-purpose vacuum pack bags, so they can be used with your vacuum packing machine, food sealer, food saver, etc., except for special models. Wide range of applications, from frozen foods to foods containing moisture‼️ Ideal for home use, restaurants, and businesses. Material: Polyethylene, Polyamide Heat resistance: 100℃ Cold resistance: -20℃ Size: 20cm x 25cm Quantity: 99 sheets Embossed for tear resistance and stretchability. Please check the instruction manual of your machine before purchasing, as it may not be compatible with some special models. I used one sheet after purchasing. It was a little too big for my household, so I am selling 99 sheets.
