VACUUM PACKAGING MACHINE

Automatic stretch-film vacuum packaging machine

Web widths from 320 to 520 mm cover fresh food, dairy, snacks and medical devices. Forming the tray from the bottom web on the machine replaces pre-made trays, cutting both packaging cost and warehouse volume.

Series overview

VACUUM PACKAGING MACHINE

Stretch-film vacuum packaging replaces pre-made trays with a continuous sequence: thermoform the tray from the bottom web, load, evacuate, seal with the top web and cut. Instead of buying a tray and a lid film, the pack becomes two films, which cuts storage volume by roughly seventy percent and lowers the cost per pack. The QJZK series offers 320, 420 and 520 mm web widths at 200–400 cycles per hour.

Medical products — syringes, surgical gowns, scalpels — demand a stricter sterile barrier, so they use a clean construction with aluminium or Tyvek lidding. Food applications such as butter, cheese and dates use cavity tooling with spray cooling, and the low residual oxygen after evacuation extends shelf life three to five times.

Applications

WHERE IT RUNS

01Fresh food and ready meals

Chilled meat, prepared vegetables and sauce packs sealed straight after forming, with less handling between steps.

02Dairy

Both pre-made trays and stretch-formed cavities for butter and cheese, giving a clean cut face with no seepage.

03Snacks

Dates, nuts and jerky in aluminium lidding that blocks light and oxygen, extending shelf life markedly.

04Medical devices

Sterile barrier packaging for syringes, gowns and scalpels with Tyvek and aluminium laminates.

Selection guide

WHAT TO DECIDE FIRST

Measure the tray first
Web width decides how many cavities fit: 320 mm suits small single cavities, 520 mm suits large trays or two cavities.
Confirm the film structure
The bottom web must stretch; the top web sets the barrier level. PE/PA coextrusion, foil and Tyvek each serve different products.
Balance vacuum and output
0.5 mbar satisfies most food applications; medical packs need validation and run slower.
Provide the utilities
Cooling water at 0.15 MPa or more and air at 0.5 MPa or more are mandatory for stretch-film models.

Frequently asked

FAQ

What vacuum level is reached?

0.5 mbar or better on stretch-film models, and 200 Pa or better on the multi-lane pouch vacuum machine, chosen by product and film.

Is cooling water required?

Yes, circulating water at 0.15 MPa or more for the sealing and forming zones.

How is tray tooling priced?

Tooling is made to the tray size and cavity count; one set covers one tray format, so a format change needs new tooling.

Are clean-room versions available?

Yes, with stainless covers, a hygienic construction and Tyvek lidding; the validation scope is agreed in the technical protocol.

How is capacity estimated?

200–400 cycles per hour multiplied by the cavities per cycle gives the hourly output, corrected for product size and evacuation time.
