The Sealing Challenge of Small Bore Containers – We Deliver the Precise Answer
In the filling and sealing lines for small seasoning sachets, oral liquid bottles, and sample cups, have you encountered these problems?
- Sealing misalignment – film fails to position accurately on small bottle mouths, resulting in incomplete seals
- Film waste – conventional sealing films offer poor fitment on small diameter containers, leading to high material loss
- Weak sealing integrity – small-volume products leak or seep oil during transit, compromising user experience
- Filling line incompatibility – sealing film does not synchronize well with high-speed small-bottle filling lines, causing frequent downtime for adjustments
Our Small Diameter Precision Heat Sealing Film is engineered specifically for 20mm+ small bore containers, delivering pinpoint sealing accuracy and robust leak protection.
Precision Sealing: The Ideal Match for Small Bore Containers
For small diameter containers, sealing precision demands are significantly higher than for standard sizes. A smaller bottle mouth means a reduced sealing area – even slight film positioning deviation can compromise seal integrity.
- Precision Dimensional Control (±0.5mm Tolerance): We offer custom small diameter sealing films starting from 20mm diameter, with dimensional tolerances controlled within ±0.5mm – ensuring every die-cut film piece lands precisely over the bottle mouth with zero offset and zero material waste.
- Tailored Heat Seal Layer Matching: Seal layer formulations are customized according to container material (PP, PET, PS, etc.), guaranteeing strong adhesion, no curling, and zero leakage. Our lab-grade material matching capabilities ensure consistent sealing quality on high-speed filling lines for small bore containers.
