澳大利亚采购需求：塑料袋、包装袋、气泡信封、聚乙烯信封、铝箔袋

I'm developing a new dry seasoning product that allows customers to marinate 250-300g of chicken, seafood, tofu, or vegetables directly in the pouch. I need a food-safe, larger foldable marinating pouch that's compliant for direct contact with raw meat and poultry. It should be leak-proof, moisture-resistant, and durable enough to hold the ingredients during shaking, as well as suitable for storing dry seasoning. Custom branding on the pouch is a must. Could you provide me with your recommendations for suitable pouch materials and sizes, along with the minimum order quantities for custom prints? I'd also appreciate estimated pricing, sampling options, and lead times for production. Looking forward to your insights!
