Frozen Food And Film Coding

Permanent date and lot marks on frozen-food film, seasoning pouches and stretch wrap without ink smear or heat damage.

Frozen Food And Film Coding

How the line is worked

Material Check

Film, frozen pouches and stretch wrap react badly to heat and wet ink.

Use 355nm cold UV on the MINI UV TTO and UV Flying Laser Printer. Original pages specify cold processing that does not damage food bags, pharmaceutical packaging or stretch films.

Line Integration

Coding heads must sit in tight film-tube or conveyor gaps.

MINI UV TTO is specified for confined spaces with a 75mm +/- 5mm working distance, 10.1 inch Linux controller, photoelectric trigger and synchronizer.

Marking

Need date, lot, barcode and QR that survive the freezer.

UV laser writes Code39, Code128, QR, Data Matrix and variable data inside a 100mm x 100mm field at up to 189 m/min (MINI UV) or 150 m/min (UV Flying).

Consumables

Ink and ribbon cost plus smear on cold film.

Laser path uses no ink or ribbon. The stretch-film case on the original site states codes print directly on snack bags with no stickers and no inks.

Fallback Inkjet

Some porous cartons still need ink.

M2 MINI and online TIJ printers remain in the catalog for cartons and bottles where laser contrast is not required. Do not treat inkjet as the frozen-film default.

Questions Buyers Ask

Why UV instead of CO2 on frozen-food film?

The UV pages specify 355nm cold processing for food bags, pharmaceutical packaging and stretch films. CO2 is specified for bottles, cartons and glass at up to 280 m/min, which is a different substrate set.

What line speed is published for UV?

MINI UV TTO: 0 to 189 m/min. UV Flying Laser Printer: 0 to 150 m/min.

Do you have a documented snack-bag install?

Yes. The Large-Format Stretch Film Coding Solution case describes a laser with a large field lens marking snack bags online with no stickers and no inks.
