We design and build water cup packing machines and full packing lines in our China factory. We focus on hygiene, repeatable fill accuracy, fast changeovers and matched downstream packing to reduce labor and boost throughput.
Water glass sealing machine — Core technologies and pain points we solve
- Hygienic filling and sealing: stainless contact parts, easy-clean surfaces and optional CIP. We prevent contamination and simplify sanitation.
- Accurate servo-driven dosing: reduce giveaway and maintain consistent fills (typical ±0.5%–2%).
- Modular, matched throughput: we align filling, bundling and case packing to avoid bottlenecks.
- Fast changeover: quick die swaps and recipe-driven controls minimize downtime for multi-SKU runs.
- Inline quality control: leak detection, checkweighers and vision inspection eliminate human error.
- Turnkey validation: we run free sample tests so you can confirm performance before purchase.
Water glass sealing machine — Equipment selection guide
For single‑serve water cups, we recommend cup filling & sealing plus downstream bundling and case packing. We exclude blister packaging (best for hardware/pharma) and stretch‑film vacuum systems (mostly for pallet/industrial wrapping or special food applications).
- Cup filling & sealing (core) — Filling & Sealing Machine and Filling Product Packaging Production Line
- Capacity: benchtop 20–200 cups/min; inline 200–600 cups/min; rotary 600–1,200+ cups/min.
- Form: PP/PS/PET rigid cups with foil/film lidding or snap lids.
- Best for: single‑serve drinking water, flavored cups, tasting/sample cups.
- Heat‑shrink bundling — Heat Shrink Packaging Machine
- Capacity: typically matches filling line; common ranges 50–600 packs/min depending on pack size.
- Form: film-wrapped multipacks (4/6/8/12).
- Best for: retail multipacks and promotional bundles.
- Case packing, boxing and sealing — Automatic Case Packer, Boxing Machine, Automatic Box Sealer
- Capacity: semi-auto ~20 cases/min; high-speed 40–120+ cases/min.
- Form: trays, cartons and sealed cases ready for palletizing.
- Best for: distribution packing and warehouse operations.
- Labeling and line integration — Unboxing, Sealing & Labeling Line
- Functions: labeling, sleeve labels, date/batch coding, checkweighers and vision inspection.
Why choose these solutions — quick comparison
| Module | Typical Capacity | Packaging Form | Key Advantage | Ideal Use |
|---|---|---|---|---|
| High‑speed rotary cup filler & sealer | 600–1,200+ cups/min | Rigid cup + foil/film | Maximum throughput, CIP options, servo control | Large bottlers and contract packers |
| Inline cup filler & sealer | 200–600 cups/min | Rigid cup + foil/film | Good balance of speed and flexibility | Medium-size producers |
| Benchtop cup filler | 20–200 cups/min | Rigid cup + foil/film | Low capex and compact footprint | Startups and pilot lines |
| Heat-shrink bundler | 50–600 packs/min | Film-wrapped multipacks | Cost-effective retail presentation | Retail multipacks and promotions |
| Auto case packer + sealer | 20–120+ cases/min | Cartons and trays | Full end-of-line automation | Distribution centers |
Water glass sealing machine — Suitable scenarios and product examples
- Vending and events: 100–250 ml PP cups with foil seals. Fast changeover and compact layout suit event setups.
