Cup-Seal Film Roll Brief: Start with the Cup, the Machine and the Opening
A cup-seal film discussion becomes more productive when the cup rim, lidding machine and opening experience are defined together.
Kaida Group shows a cup-seal film roll in its roll-film range. For a new cup product, the film cannot be specified from a cup diameter alone. The cup rim, sealing equipment, filled product and way a customer opens the pack all belong in the same brief.
Record the actual cup and rim
Send a drawing or sample of the cup that will be used in production. Include the outside rim dimensions, shape, rim width, material supplied by the cup maker and any variation between cup sizes. If the range uses more than one cup, list each size separately. A clear photo next to a ruler helps the first discussion, but a physical cup sample is more useful for fit checks.
State the fill level and headspace. A film that sits above a liquid, sauce or dry product may face different splashing, contamination and handling conditions on the line. Explain whether the cup is sealed immediately after filling and how it is carried away.
Describe the lidding operation
Identify the lidding machine, its operating mode and the roll dimensions it accepts. Share the current film width, core size, unwind direction, print repeat and registration method if those are available. For a new machine, ask the equipment supplier for its film specification before approving artwork or ordering a roll.
Discuss the seal pattern and the space needed for a pull tab. The rim must be clean enough for the proposed sealing process, and the film must feed and register consistently. A short line trial with the real cup and product is the practical way to review these points.
Define the opening experience
Decide whether the consumer should peel the lid, pierce it or use a straw. If it is peeled, describe the desired opening force and whether a visible tab is needed. Also consider what happens after opening: does the consumer drink immediately, pour, or carry the cup to another place?
Put mandatory product information, brand artwork and the opening cue on a cup-top layout at actual size. Small circular areas fill up quickly, especially when multiple languages or a barcode are required.
What to send for a useful quotation
- Cup samples or drawings for every size in the range.
- Product type, fill level and target storage route.
- Lidding machine model and existing roll specification.
- Opening method, tab preference and sample artwork.
- Expected trial quantity and the approval checks your team will run.
Use these inputs to review a proposed roll specification and a trial plan with Kaida Group.
