The choice of materials for fully automatic vacuum packaging machines mainly depends on what you are packaging, with corrosion resistance and hygiene standards being the core considerations. Below are specific materials and applicable scenarios:
Main Materials and Applicable Scenarios
304 Stainless Steel
Features: Corrosion resistant, wear resistant, easy to clean, meets food hygiene standards.
Applications: Packaging foods with broth, salt, or acidic components (such as meat, seafood, sauces), and pharmaceutical and chemical products. For example, Haohe Packaging's 304 stainless steel models are suitable for various materials.
Aluminum Alloy/Aluminum-Magnesium Alloy
Features: Lightweight, low cost, but weaker corrosion resistance.
Applications: Packaging dry, non-corrosive solid or granular materials (such as rice, snacks, hardware).
Food-Grade Plastic
Features: Lightweight, insulating, corrosion resistant, but lower strength.
Applications: Small tabletop or household packaging machines for packaging dry foods.
