意大利采购需求：压纹真空袋，食品储存，密封包装，真空低温烹调，真空封口机，餐食准备

We are looking to purchase large sous vide bags suitable for use in an autoclave at temperatures reaching 104 degrees Celsius. It's essential that the bags maintain their integrity under these conditions, so we would appreciate guidance on the specifications and materials you can offer. If large sizes aren't available, we are open to the possibility of sourcing the raw materials from you and sealing the bags ourselves. Please provide information about available options, including any minimum order quantities, pricing, and lead times. We're eager to find a reliable solution that meets our needs, so any additional details you can share would be greatly appreciated.
