Technical FAQ
These questions help buyers prepare product samples, layout data, film requirements, and automation expectations before requesting a machine configuration.
What package sizes can the SW-L450 L bar shrink wrapper handle?
The SW-L450 is specified for products up to 330 mm wide and 130 mm high, with width plus height not exceeding 400 mm and length plus height not exceeding 500 mm. Buyers should confirm their longest carton, film overlap, and expected shrink clearance before final line selection.
Which shrink film is recommended for this machine?
The listed film type is center-folded polyolefin film, commonly used for clean retail-style wrapping of boxes, cosmetics, electronics, food packs, and gift products. Film width and outer roll diameter should match the listed 530 mm by 280 mm maximum roll range.
How does the L bar sealing system support packaging consistency?
The L shape sealing blade forms a full seal in one cycle, while positioning guidance, product detection sensors, and adjustable table dimensions help keep different box sizes aligned. This is useful when buyers need repeatable sealing and shrinking across mixed carton runs.
Can the SW-L450 be connected with upstream feeding equipment?
The product page lists optional accessories such as an extra conveyor belt, extended in-feeding system, and special in-feeding mechanism. These options can support automatic stacking, bundle forming, and smoother transfer into the sealing area when the project requires a more continuous line.
What should procurement teams check before ordering?
Teams should provide sample product dimensions, pack weight, desired film type, hourly output target, available voltage, layout space, and whether products arrive manually or from an upstream conveyor. These details help confirm tunnel width, sealing clearance, and feeding configuration.
What applications are suitable for this economical shrink wrapper?
The SW-L450 is positioned for food, cosmetics, hardware, electronic components, gift boxes, pizza boxes, cartons, and similar boxed goods. It is most suitable when the buyer needs sealed shrink packaging with practical output and controlled investment cost.
