Overview of Packaging Machinery
Packaging machinery serves as indispensable core automation equipment for modern industry, food processing and manufacturing. By means of heat‑sealing, vacuuming, gas flushing, film wrapping and heat shrinking, these machines encapsulate products safely and hygienically. They effectively extend product shelf‑life, improve packaging visual performance and raise overall production‑line efficiency.
Founded in December 1989, Zhejiang Dongfeng Packing Machine Co., Ltd. owns a 26,800‑square‑meter modern factory with an annual output capacity of 200,000 sets. Its products are sold to more than 100 countries and regions across the globe.
Main Categories of Packaging Equipment
1. Vacuum Packing Machines
- Tabletop & Commercial Vacuum Packing Machines: Models DZ‑260H and DZ‑300T are built for restaurants, delis and limited‑space scenarios. They deliver up to 99.9% vacuum level and feature soft‑air return to prevent deformation of soft goods.
- Industrial Double Chamber Vacuum Packing Machines: DZQ‑400/500/600 series adopt dual‑chamber alternating‑operation design for mass food‑plant production. Gas‑flush function supports modified‑atmosphere packaging to preserve product flavour and shape.
- Chamber Belt Vacuum Packing Machine DZQ‑800C: Designed for high‑volume continuous automatic production. It is equipped with automatic infeed conveyor, hygienic easy‑to‑clean structure, and supports single‑seal, double‑seal and seal‑and‑cut modes.
2. Film Wrapping and Tray Sealing Lines
- Cling Film Wrapper: Manual HW‑450 and automatic iWrap series handle fruits, vegetables, meat and mushrooms. Automatic units reach 10‑15 packs per minute and reduce consumable waste.
- MAP Tray Sealer QT‑700S: Injects mixed oxygen, carbon dioxide and nitrogen before tray sealing to greatly extend shelf‑life for ready‑to‑eat meals and fresh food.
- Skin Vacuum Tray Sealer: Manual ZT‑260 and rotary double‑station ZT‑480 apply high‑barrier skin film for steak and seafood. It locks juices and creates striking 3‑D merchandising effects.
- Thermoforming Vacuum Packer DDLZ‑420A / 520A: Equipped with Siemens PLC and Omron photoelectric sensors. It completes bottom‑film thermoforming, filling, lidding, vacuuming and sealing in one fully‑automated workflow.
3. Shrinking and Drying Equipment
The ST‑6050 hot‑water dip tank is a matching shrink unit for vacuum packers. Full hot‑water immersion delivers uniform dead‑angle‑free shrinking. Mounted on heavy‑duty casters, it saves floor space and suits medium‑to‑large‑sized goods.
4. Full‑Scale Automated Packaging Line: DZQ‑800C + ST‑8031 + FG‑1554
- Step 1 DZQ‑800C: High‑speed continuous vacuum packaging with automatic product infeed.
- Step 2 ST‑8031: Continuous hot‑water tunnel shrinking without intermediate transfer conveyor.
- Step 3 FG‑1554: Cold‑air tunnel drying removes residual moisture from finished packages.
5. Sealing, Filling and Coding Machines
- Sealing equipment: PFS hand sealers, PS‑450 pedal sealers, DBF‑770W continuous band sealer and DGYF‑500A electromagnetic induction foil sealer for bottle necks.
- Filling & coding: DFJ‑130 and SPF piston fillers deliver ±1% precision for low‑ and high‑viscosity materials. HP‑130 ribbon coders and MY‑380 ink‑wheel coders print production dates and batch numbers.
6. OEM Custom‑Engineered Solutions
Beyond standard off‑the‑shelf machines, Dongfeng Packing provides custom‑built equipment tailored to client production conditions:
- Custom vacuum‑chamber dimensions including deep concave chambers for bulky products.
- Optional vacuum pumps: standard in‑house pumps or upgraded German Busch high‑capacity pumps.
- Custom moulds, tray dimensions and pallet layouts for MAP tray‑sealing systems.
- Regional‑compliance adaptation: custom voltages, power plugs and electrical standards to satisfy local international trade requirements.
