Advice and support as recipe for success
This product is made using high-quality foil laminate, allowing your creativity to run free. Printing in multiple colours using flexo and gravure printing, as well as foil embossing and coloured embossed reliefs are produced at our location by us. If you are not familiar with all of these techniques, do not hesitate to ask us about them. We will be happy to advise and support you with any questions you may have about the production and design of your caps.
A Polycap is a roll-on cap made of polylaminate film (aluminIum composite film):
- Material – multilayer aluminum composite film (polylaminate), a combination of aluminum and plastic layers
- Application – applied to the bottle neck via a roll-on process
- Flexibility – suitable for various bottle shapes and necks
Typical applications: wine, spirits, and other premium bottled products
The processing of polylaminate caps (Polycap) is identical to that of Alucap or tincap:
- Crimping – The cap is applied to the bottle neck via a crimping process
- Automatic – Fully integrable into existing automatic filling lines
- Manual – Also possible using a bench-top crimper for small filling volumes
- The capping machine and capping head must be adapted to the respective cap type and bottle neck.
Wrinkling is usually caused by three factors:
- Incorrect proportions – the cap does not fit the bottle perfectly; the cap’s inner diameter is too large or too small in relation to the bottle neck
- Bottle neck geometry – irregular, conical, or particularly slender bottle necks increase the risk of wrinkling → The cap size must be precisely matched to the bottle geometry
- Incorrect machine settings – incorrect roll-on pressure, incorrect speed, or worn rollers and rubber rings on the rolling machine
Creasing can be reliably prevented by early coordination of cap size, bottle geometry, and machine settings. The BT-Watzke team is happy to assist with error analysis and optimization.
No – when used properly, Polycap capsules do not affect the contents of the bottle:
- No direct contact with the contents of the bottle – the capsule seals the bottle opening from the outside
- All materials and laminates used meet food safety requirements in accordance with EN ISO 22000:2018
For your safety, we recommend using certified products and adhering to the recommended storage and handling conditions.
Proper storage ensures optimal workability and appearance until application:
- Temperature: 10–35 °C – Avoid frost and direct heat sources
- Storage: dry, sealed, and dust-free – keep original packaging sealed until use
- Humidity: 30–80% relative humidity – prevent condensation
These specifications apply exclusively to not applied product – i.e., capsules before applied on the bottle.
