Verified roll-fed liquid sachet model

LU-GJH1000 Automatic Water Sachet Packing Machine

A compact vertical form-fill-seal machine for 50–500 ml drinking-water sachets and other approved free-flowing liquids, using single-layer PE roll film and a back/centre seal.

Direct answer

What is the LU-GJH1000?

The Lancing LU-GJH1000 is an automatic roll-fed liquid sachet machine that feeds a PE film web, exposes the web to ultraviolet light, forms a back-sealed sachet, meters the approved liquid, applies date or batch coding, heat-seals the pack and cuts the finished sachet. The UV stage treats the packaging film web; it does not treat or sterilise the water.

Final suitability depends on the water feed, fill volumes and tolerances, film construction, finished sachet drawing, production duty, destination and agreed test method.

How the LU-GJH1000 process works

  1. Film feed: approved roll film is held, guided and drawn through the machine.
  2. Film-web treatment: the packaging film passes the ultraviolet treatment stage before forming.
  3. Sachet forming: the PE web is formed around the forming section and receives a longitudinal back/centre seal.
  4. Liquid metering: the integrated pump and product path meter the approved free-flowing liquid.
  5. Coding: the agreed date or batch information is applied, subject to final code format and consumables.
  6. Sealing and cutting: transverse top and bottom seals are formed before the finished sachet is cut.

The customer provides potable water at the approved temperature, flow, head or pressure and connection. Storage, filtration, reverse osmosis, pasteurisation, microbiological control and other upstream water-treatment duties remain outside the sachet machine unless separately defined.

Film and finished-sachet information required before manufacture

The nominal film-width and pack-size ranges do not replace a production drawing. Provide the PE grade and gauge, reel and core dimensions, print repeat, registration mark, seal width, code position, cut position and any tear or notch requirement. Representative film is needed to confirm transport, forming, sealing, registration and cutting.

Food-contact suitability and any written declaration required for the intended market remain the responsibility of the pack owner and film supply chain. The final laminate or single-layer film must be approved as part of the technical schedule.

How should output be confirmed?

The stated 33–37 sachets per minute is a nominal model reference, not a guarantee for every fill and film. Confirm the required saleable output against the actual volume, water conditions, sachet dimensions, film, code, normal replenishment and downstream collection method.

An acceptance test should identify the run duration, sample frequency, permitted fill tolerance, seal and leak-test method, code check, rejected packs and any normal stops included in the calculation. This separates machine cycle rate from accepted production output.

Site and line-boundary requirements

The standard electrical reference is 220–240 V, single phase, 50 Hz, with approximately 1.6 kW installed power; the final plug, isolator and destination compatibility must be confirmed. The machine is approximately 700 × 740 × 1,740 mm and 275 kg, so the layout must include delivery access, safe operator space, reel loading, cleaning, maintenance, drainage and finished-sachet removal.

Downstream collection, conveying, drying, counting, cartoning or case packing must be defined separately. For projects using several identical machines, line balancing, operator access, shared utilities, collection capacity and spare-parts strategy should be assessed as one system.

Buyer questions

LU-GJH1000 water sachet machine questions

Does the LU-GJH1000 sterilise the drinking water?

No. The integrated ultraviolet stage is for the packaging film web. Potable-water production, treatment, filtration, storage and microbiological control are separate upstream responsibilities.

Can the machine pack every liquid between 50 and 500 ml?

No. The range is a model reference for drinking water and other approved free-flowing liquids. Product chemistry, viscosity, temperature, foaming and compatibility still require review and testing.

Can printed film be used?

The final film, print repeat and registration mark must be specified and tested. Coding, eye-mark control and cut position need to be agreed against the finished artwork and machine configuration.

How is fill performance checked?

Agree nominal volumes, tolerances, sampling frequency and the volume or weight conversion method before the trial. Record water conditions, settings, time and rejected packs.

What finished-pack checks are needed?

Typical checks cover dimensions, code, cut position, visible seal defects and the pack owner’s approved seal-integrity or leak-test method. The acceptance rules must be defined for the project.

What must be ready before a water and film trial?

Provide representative water, production-intent PE film, the finished sachet drawing, all fill volumes, code data, test methods and sufficient material for the agreed run.
