Custom Cling Film Cores for Converters

What size core does cling film use?

Production and catering rolls usually run on 2-inch (50 mm) or 3-inch (76 mm) cores, while household rolls use smaller custom sizes set by the box and rewinder.

What is the core of cling film made of?

It’s made of layers of paper wound and glued into a rigid tube, then cut to the roll’s length.

What is the difference between cling film and stretch film?

Cling film is a thin film for wrapping food, while stretch film is a thicker film used to wrap and secure pallets.

Are cling film cores food safe?

The core doesn’t touch the food directly, but it should have a clean surface and dust-free edges so nothing transfers to the film wound on it.

Can cling film cores be custom made?

Yes, MAMPACK makes cores to your drawing, with custom inside diameter, wall thickness, and length.

Cling film gets touched by food, by chefs, and by shoppers who never think about what’s inside the roll. You do, though, or you wouldn’t be here. Somewhere between the rewinder and the dispenser box, the core decides how that roll behaves. The right cling film cores are easy to forget. The wrong ones aren’t. Do you know which kind you’re running? 

What Is a Cling Film Cores?

It’s the paper tube cling film is wound on, from the large rolls coming off the production line to the small ones that end up in a kitchen drawer.

• Also called: a food wrap core or a cling film paper tube.
• Main job: keep thin film wound evenly so it unrolls without tearing.
• Why it’s different: it sits right under film that touches food, so cleanliness matters more than on most cores.
• Build: layers of paper wound and glued into a rigid tube, then cut to length.

Catering Rolls vs Household Rolls

Same film, two very different rolls. The core changes with who uses the roll and how often.

 

Catering cling film core	Household food wrap core
Roll size	Wider, heavier rolls for kitchens and food service
How it’s used	Pulled many times a day, often from a dispenser
Main need	Strength and clean edges under frequent pulling

What Does a Core Need for Food-Contact Film?

The core doesn’t touch the food, but the film wound on it does. That’s why cling film cores are judged on cleanliness as much as strength.

Clean Surface and Dust-Free Cutting

Paper dust and loose fibers are the main risk here. They come from rough cuts and travel straight into the first layers of film.

• Smooth outer surface: nothing that transfers to the film during winding.
• Clean cut ends: no burrs or loose fibers at the edges.
• Why it matters more here: PVC film is thin and clingy, so a PVC cling film core with a rough edge passes every speck of dust into the roll.
• What to ask: edge quality checked before delivery, plus clean packing so cores arrive the way they left the factory.

Moisture Control and Dimensional Stability

Paper reacts to the air around it. A cling film core that swells or shrinks changes how the film winds and how the finished roll fits its box.

• MAMPACK’s range: moisture held at 4 to 7 percent under controlled drying.
• Too damp: the core softens and the ID can swell, so it may not load on the rewinder.
• Size drift: a core that changes size can leave household rolls loose or jammed in their boxes.
• Storage: keep cores sealed and off the floor, especially in humid months.

Which Core Size Fits Your Cling Film Rolls?

Your rewinder sets the inside diameter, and the roll type sets the length. Here are the core options MAMPACK makes and where each one fits.

 

Roll type	Core option	What to check first
Production rolls	3″ (76 mm) standard	Wall strength for the roll weight
Catering rolls	2″ (50 mm) or 3″ (76 mm) standard	ID fit on your rewinder and dispenser
Household rolls	Custom ID and length, made to drawing	Fit inside the retail box

• Wall thickness: from 3 to 20 mm.
• Length: cut to order, from 1 cm to 10 m.
• Dispensers: some catering dispensers hold the roll by its core, so a catering cling film core needs an ID that fits the dispenser too.
• Common mistake: most size problems with cling film cores come from copying an old order instead of measuring the current machine.

How Is a Food Stretch Film Core Different From an Industrial One?

Both carry stretch film, but one wraps sandwiches and the other wraps pallets. That difference changes almost everything the core has to do.

 

Food stretch film core	Industrial stretch film core
Film	Thin PVC or PE cling film
Roll weight	Lighter
Winding tension	Lower
Top priority	Clean surface and dust-free edges

 

A PVC cling film core rarely fails from crushing. It fails from dust, moisture, or a loose fit. For pallet film, see our guide to stretch film cores.
