Hey,

I’m looking to buy a cup sealing machine and could use some advice before I commit.

I’m planning to use:

• PP cups (95mm)
• PET cups (98mm)

and I want the final product to have a peelable seal with an easy-to-grab tab.

From what I understand so far:

• The seal itself (peelable vs not) mainly comes from the type of film, not just the machine
• Machines use heat + pressure + a cutting mechanism to seal and trim the film
• Cup/film compatibility matters (PP with PP film, PET with PET film, etc.)

Where I’m confused:

• How do you actually get the peel tab?
• Is that something built into the machine (like a special cutting die), or can you add a separate part to a standard sealer?
• Or is it done through the film design itself?

I’ve seen some suppliers mention “custom machines with peel tabs,” which makes it sound like it’s part of the tooling rather than a universal add-on

Ideally I’d like to:

• Buy a standard machine that can handle both PP (95mm) and/or PET (98mm)
• Use peelable film
• Add or upgrade later to get a proper tab if possible

If anyone has experience with this:

• Is a universal machine + peelable film enough?
• Or do I need to plan for custom molds/dies from the start?
• Any recommended suppliers or machines that support this?

Appreciate any help, this part has been way harder to figure out than expected.
