Vacuum Packaging Solutions - Wenzhou Dajiang Vacuum Packaging Machinery Co., Ltd.

Core Function: Removes air from a flexible vacuum bag (made of plastic or multi-layer films) and heat-seals the opening, creating an airtight barrier. This locks out oxygen to preserve contents.

Ideal Products:
·Food items (meats, cheeses, grains, dried fruits, cooked meals).
·Non-food goods (electronics, fabrics, documents) needing moisture/dust protection.

Basic Process:
·Place the product inside a vacuum bag (leave extra space at the top).
·Insert the bag’s open end into the vacuum machine.
·The machine suctions out air from the bag.
·Once fully vacuumed, the machine heat-seals the opening to lock in the seal.

Key Benefits:
·Extends shelf life (slows spoilage/mold in food; prevents oxidation in non-food items).
·Saves space (compressed packaging reduces storage/transport bulk).
·Prevents freezer burn (for frozen foods).
·Versatile (bags come in various sizes for small to large items).
Suitable Scenarios: Home use, small delis, meat processors, online food sellers, and storage facilities.

Selecting Vacuum Packaging Machine Models Based on Output, Bag Size, and Product Weight

Small-Scale

·Daily Output: <500 packs
·Bag Sizes Handled: Small to medium (e.g., 10×15cm to 30×40cm)
·Product Weight Range: Light to medium (<2kg) – ideal for individual portions (e.g., 200g cheese slices, 500g chicken breasts, or 1kg dried nuts).
·Best For: Home users, small delis, or cafes.
·Features: Compact design with manual loading; basic vacuum strength (sufficient for lightweight items). Affordable and easy to operate.
·Suitable machines: Tabletop vacuum packaging machine, like DZ-260PD, DZ-300PJ , DZ-400G, etc. And Floor type vacuum packaging machine, like DZ-400/2E or DZ-500B

Medium-Scale

·Daily Output: 500–3,000 packs
·Bag Sizes Handled: Medium to large (e.g., 20×30cm to 50×70cm)
·Product Weight Range: Medium to heavy (2kg–10kg) – suitable for bulk food (e.g., 5kg ground beef, 8kg rice bags) or non-food items (e.g., 3kg hardware kits).
·Best For: Meat processors, bakeries, or small warehouses.
·Features: Automated conveyor feeding; stronger vacuum pumps to compress denser products. Adjustable seal strength to handle thicker bags for heavy items.
·Suitable machines: Tabletop vacuum packaging machine, like DZ-450A or DZ-500T. And floor type vacuum packaging machine, DZ-800,DZ-500/2G,DZ-600/2G. And vertical vacuum packaging machine, like DZ-500L.
