Outdoor Application Label Material Manufacturers

Zhejiang Guanma Packaging Co., Ltd. is a self-adhesive paper and film material manufacturer based in Jiaxing, Zhejiang, close to Shanghai. As an Outdoor Application Label Material manufacturer, we coat, slit and print label stock for labels that stay in sunlight, rain, dust and temperature swings, supplying it either as jumbo rolls for converters or as finished die-cut and printed labels.

In this product family the print is rarely the failure point. What decides service life is the face stock, the adhesive chemistry and the liner working together on the actual substrate: a low-surface-energy silage film, a curved battery casing, an aluminium asset plate or a painted steel frame.

The Outdoor Range at a Glance

Each construction is a defined combination of face stock, adhesive and release liner. The table shows the current build of each item so a project can be matched to an existing construction before any customisation is discussed.

A 75 µm matt white synthetic PP film is also available as an inkjet-printable stock, allowing short-run outdoor marking and identification work to be produced in-house without offset tooling.

Face Stock Selection by Exposure Profile

PET film for durable, dimensionally stable labels

Polyester is the workhorse of the durable side of the range. Combined with UV-curable adhesive, our PET constructions are built for UV resistance, solvent resistance, heat resistance and slow ageing. Surface thickness and appearance are chosen per end use: 100 µm bright white for opacity and stiffness, 50 µm transparent for clarity, 50 µm matt silver where a metallic look is required, and a 50 µm bright white grade formulated for a wide high/low temperature band.

End uses include solar panels, lithium battery casings, fixed-asset labels, 3C products and electric tools, where the label must stay legible and in place for years and often has to resist cleaning agents and process solvents.

PVC and PE vinyl for flexible, uneven surfaces

White PVC vinyl brings high tensile strength, flexibility and good conformity, so it follows curved and irregular surfaces instead of lifting at the edges. The 80 µm UV-resistant white PE film label stock takes the same approach on softer, more stretchable surfaces: it moves with the film beneath it rather than fighting it, which is what agricultural bale wrap demands.

Adhesive Systems for Outdoor Service

Adhesive choice is where most outdoor label projects are won or lost. We coat acrylic, hot melt, removable, solvent-based, high/low temperature resistant and UV-curable systems, and select between them by substrate and climate rather than by habit.

• UV-curable adhesive: solvent-free, no VOC, non-whitening, high clarity, fast build-up of bond strength; well suited to clear and bright PET constructions and to projects with lower customisation minimums.
• Extra high-tack permanent solvent adhesive: the choice for low-surface-energy polyethylene and LLDPE films, with UV and high/low temperature resistance for field exposure.
• Water-based acrylic: a general-purpose permanent option for paper and film faces on smoother, higher-energy surfaces.
• Removable systems: for labels that must come off cleanly without residue, such as temporary asset marking or returnable equipment.

The 100 µm bright white PET film with UV adhesive shows how face and adhesive are specified together: the film holds the print, the adhesive holds the film, and the liner has to release cleanly at the speed of the applicator.

Where These Constructions Fit

Outdoor labelling projects rarely share one failure mode, so the range is grouped by the conditions the label actually meets.

• Agricultural bale wrap: silage wrap and cotton baling film, where extra high-tack adhesive, flexibility and abrasion resistance matter more than print gloss.
• Energy and battery hardware: solar panels and lithium battery casings, where UV, solvent and heat resistance keep identification readable.
• Fixed assets and industrial equipment: asset tags, machinery plates and electric tools that are cleaned, handled and left in daylight.
• Electronics and 3C products: durable labels that must stay flat and legible on small, sometimes curved housings.
• Field sealing and splicing: double-sided high-tack tape for joining bale wrap in the field, with no excessive adhesive bleed onto the crop.

The same base materials also support adjacent programmes such as tyre label material and industrial identification work, where the surface and the exposure profile are simply different.

Roll Formats, Slitting and Printing

Outdoor stock is supplied as jumbo rolls at 1070 mm width, or slit down to the width your press or applicator runs, for example 210 mm, 215 mm or 330 mm. Finished label rolls in sizes such as 50 × 70 mm and 80 × 100 mm are produced on our die-cutting equipment, and other formats are built to the drawing or sample supplied with the order.

For printed work we run flexographic, offset, screen, digital UV inkjet and thermal transfer processes. That means a project can be sourced as blank die-cut unprinted labels, as printed finished labels, or as plain master rolls for your own converting line.

Quality Control and Acceptance Records

Every order passes through four recorded checkpoints: incoming raw material inspection, coating, mother roll slitting and final packaging. Detailed inspection records are retained through each stage, so a delivered roll can be traced back to its coating run and its incoming film batch.

Our quality management system is certified to ISO 9001, and we hold a GFA certificate. Where a project needs agreed acceptance criteria, we work from a signed sample or a written specification covering face stock thickness, adhesive type, liner, roll dimensions and print requirements, and the finished goods are checked against that document.

Information We Use to Configure Your Solution

A workable proposal starts from the application, not from a stock list. These are the inputs that let us choose a construction and quote it accurately.

Frequently Asked Questions

Which face stock holds up best to years of direct sunlight?

For rigid, dimensionally stable surfaces we recommend PET film with UV-curable adhesive, which combines UV resistance, solvent resistance and heat resistance with slow ageing. For flexible or uneven surfaces, UV-resistant PVC vinyl or the 80 µm white PE film with extra high-tack solvent adhesive conforms better and resists edge lift.

Why is the adhesive decisive on silage and cotton bale wrap?

PE and LLDPE wrap are low-surface-energy films, so a standard permanent adhesive may look bonded but release under tension. Our PE8MY60 and PVC8MK60 constructions use extra high-tack permanent solvent adhesive with high/low temperature and UV resistance, and the flexible face stretches with the wrap instead of splitting away from it.

What is the practical difference between the UV-curable adhesive and the high-tack solvent adhesive?

UV-curable adhesive is solvent-free with no VOC, does not whiten, keeps excellent clarity and builds bond strength quickly, which suits clear and bright PET constructions. The high-tack solvent system is built for the hardest low-energy substrates and for field conditions where initial grab and temperature tolerance matter most.

Can we order jumbo rolls without printing, or only finished labels?

Both are standard. We supply master rolls at 1070 mm width, custom slit rolls for your press, blank die-cut unprinted labels and fully printed finished labels run by flexo, offset, screen, digital UV inkjet or thermal transfer.

How is an outdoor construction verified before a full run?

We prepare a sample against the declared substrate, adhesive, liner and format, and production then follows the approved sample with recorded checks at incoming material, coating, slitting and packaging. Standard production scheduling on these constructions typically runs 7 to 15 days once the specification is fixed.
