UNIVERSA 250 is a fully automatic pre-stretch film rewinder for converting standard stretch film into pre-stretched rolls with minimal operator involvement. It runs at up to 1,200 m/min and produces finished rolls from 320 to 620 mm wide.
The machine loads cores automatically, fixes the film to the core, winds to length, cuts the film and removes the finished roll, with a choice of roll delivery systems. It also works as a multi-functional automatic high-speed rewinder, so the same machine can make standard and pre-stretched hand rolls.

Why pre-stretched film
Pre-stretched film has already been elongated on the machine, so the person wrapping a pallet by hand does not have to stretch it. The roll is lighter, easier to handle, and covers more metres per kilogram – a product that end users notice and distributors can sell at a better margin.
Who UNIVERSA 250 is for
- Stretch film producers adding pre-stretched rolls to their range
- Distributors who want to offer pre-stretched rolls without buying them in
- Converters who need one machine for both standard and pre-stretched rolls

How UNIVERSA 250 works
- A jumbo roll 300–600 mm wide and up to Ø480 mm is mounted on its 76 mm core.
- The machine loads a core automatically and fixes the film to it.
- The film is pre-stretched and wound to the set length at up to 1,200 m/min.
- The film is cut and the finished roll is removed through the selected delivery system.
- A new core is loaded and the next cycle starts – 1 s for a 12 m roll.
Standard and pre-stretched rolls from one machine
UNIVERSA 250 also works as a multi-functional automatic high-speed rewinder. A producer can run pre-stretched rolls when orders come in and switch to standard hand rolls the rest of the time, so the machine does not stand idle when demand for one product drops.
Roll formats explained
Most stretch film is sold in three formats, and a rewinder is what turns the first into the other two:
- Jumbo (mother) rolls come straight off the extrusion line, usually on 76 mm cores. They are too large and heavy to wrap pallets with.
- Hand rolls are short, light rolls for manual wrapping, typically on small cores so they can be held on a handle or dispenser.
- Machine rolls are longer, heavier rolls for pallet wrapping machines. Bronse pallet wrappers, for example, take rolls 500 mm wide, up to Ø250 mm and 16 kg on 76 mm cores.
Roll weight is easy to estimate: weight (kg) ≈ width (m) × length (m) × thickness (micron) × 0.92 ÷ 1,000. A 500 mm × 300 m × 17 micron hand roll weighs about 2.3 kg; a 500 mm × 1,500 m × 23 micron machine roll about 16 kg.
What to look for in a pre-stretched roll
- Even stretch across the full width, so the film does not neck or tear when used.
- Enough holding force left in the film to secure the load.
- A light roll that is easy to handle for a full shift.
- Consistent length from roll to roll.
Preparing your site for the UNIVERSA 250
Everything you need to plan the installation is in the catalogue values:
- Electricity: 380 V, 3P + N + G, 50/60 Hz, 20 kW installed power (nominal consumption 20 kWh).
- Compressed air: 6–8 bar, 130 Nl/min. Clean, dry air keeps pneumatic parts working longer.
- Floor space: 1765 × 2600 mm footprint, 2000 mm high for the machine itself, plus room to bring in jumbo rolls, take finished rolls away and let the operator move around.
- Floor load: net weight 2,100 kg.
- Jumbo handling: jumbo rolls weigh up to 70 kg, so plan how they reach the machine – a hoist, lifting trolley or crane.
Frequently asked questions
Which film can UNIVERSA 250 process?
Film from 15 to 35 micron, from jumbo rolls 300–600 mm wide and up to Ø480 mm.
Does UNIVERSA 250 need many operators?
No. Core loading, film fixing, cutting and roll removal are automatic, so the machine runs with little operator involvement.
Can it make standard rolls too?
Yes. It can also work as a multi-functional automatic high-speed stretch film rewinder.
Which finished roll widths are possible?
From 320 to 620 mm, up to Ø250 mm, on 38, 50 or 76 mm cores.
Is UNIVERSA 250 suitable for a distributor?
Yes. Distributors use it to make pre-stretched rolls themselves instead of buying them in, and to make standard hand rolls on the same machine.
