1. Define the product envelope
Record the minimum, nominal and maximum product length, width, height and weight. Include shape, centre of gravity, fragility, surface friction, temperature, residue and whether the product can roll, bounce or deform.
Provide actual production samples rather than only perfect laboratory examples. A wrapper must handle normal process variation.
2. Define the finished pack
Set the required bag length and width, longitudinal seal position, end-seal appearance, film transparency, artwork registration, coding, opening features and any barrier or shelf-life target.
Distinguish mandatory requirements from preferences. That helps engineering focus on pack quality and production reliability.
3. Set a sustained output target
Specify packs per minute over a defined run, not only an instantaneous peak. Include expected stoppages, film changes, product changeovers, quality checks and upstream availability.
The LUZB350X is listed at 30–120 bags per minute, while the LU-WP550A wet-wipes line is listed at 30–80 packs per minute. These are reference ranges, not guarantees for every format.
4. Choose the feeding concept
Manual loading may suit lower-volume or variable applications. Lugged, flighted or automatic feeding supports higher output when product arrives in a predictable orientation. Random products may require a feeder, vision system, robot or collator.
5. Supply the real film specification
Provide the technical data sheet, reel dimensions, unwind direction, print repeat and eye-mark details. A generic label such as “OPP” does not describe the sealant layer, friction, stiffness or operating window.
6. Map every interface
Define upstream transfers, accumulation, code verification, checkweighing, metal detection, reject confirmation, downstream conveying, case packing and production-data signals. Mechanical and control interfaces should be documented together.
7. Agree acceptance criteria
Create a factory and site acceptance plan using representative products and film. Include sustained rate, seal and cut position, pack appearance, code quality, alarm handling and agreed changeovers.
8. Confirm the support scope
Clarify delivery, offloading, positioning, utilities, installation, commissioning, training, documentation, spare parts and response arrangements. Lancing’s service pages describe installation and commissioning support for packaging machinery projects.
