There are many factors that could cause a thermal label to print a clear barcode and not function during use. Could fall out of a cold carton, roll into the printer, become unreadable due to abrasion or leave an adhesive residue on reusable packaging.

Quindi, the label size cannot be the only criterion used to choose thermal label paper. The printing technique, Faccia, rivestimento, adhesive and release liner must be matched, from the point of the buyer requesting the labels, to the complete labeling process.

In the event you are interested in printing directly from the thermometer, begin with a Direct Thermal or Thermal Transfer Printing method.

Thermal paper is coated with a heat-sensitive material that turns dark when it comes in contact with the printhead. Does not require ribbon and can be used for fast-moving shipping labels, retail price labels and food rotation labels, as well as for labelling in warehouses for a brief period.

The thermal transfer printing method involves transferring an image to a coated paper or synthetic surface with a ribbon. It is generally desired in cases where labels have to be exposed to severe conditions or have to resist exposure for a longer duration.

Before sourcing, conferma:

• Printer technology
• Required image life
• Printing speed
• Barcode density
• Use as either an indoor or outdoor fertilizer.
• Calore, light or chemicals can cause them to become exposed.

Jinbao's direct thermal label range is tailored to the logistic, retail and warehouse market without the need for the use of a ribbon.

Select the appropriate Facestock for the handling conditions.

Paper facestock is cheaper and suitable for use on cartons, envelopes, shelves and every day retail packaging. Tuttavia, regular thermal paper might not be adequate for wet, grease or extremely abrasive applications.

The top coated thermal paper provides additional protection, increasing moisture resistance, oil resistance, scratch resistance and resistance to frequent handling. Synthetic thermal material offers better resistance to tearing, but is generally higher in price and is used for industrial, cold-chain or outdoor applications.

Select the simplest label material that will meet the desired label life. A heavy duty synthetic label is not really operational value for a same day parcel and is a cost on top of the cost.

Determine if a protective coating is needed.

For short storage term in dry conditions (indoor), uncoated or eco thermal label paper is usually applicable. Examples of typical applications are supermarket weighing labels, temporary inventory labels and parcels for fast delivery.

The more important the top or semi-top coating is when the labels come up against:

• Condensation or rain
• Grease and handling dirt
• Surface abrasion
• Alcohol-based cleaners
• Longer transportation cycles
• Repeated barcode scanning

Exposed logistics applications can be provided with waterproof, oil resistant and scratch resistant carta per etichette termiche patinata by Jinbao.

When selecting the adhesive, you should take into account the following factors:

A good glue will not stick as well on all packages. The adhesion is affected by carton texture, plastic types, surface energy, application temp. and storage conditions.

Permanent adhesive is the most frequently used adhesive for shipping cartons, parcels and retail packaging. Remove-able adhesive is preferred for temporary price tags and reusable items and surfaces that need to be kept clean. Freezer adhesive is designed to be used in low-temperature environments.

Buyers should identify:

• The material has a glass, metallo, cardboard or plastic surface.
• Flat and/or curved packaging.
• The surface should be smooth, rough or dusty.
• Application temperature
• Lowest service temperature
• Required removal behavior

Use test labels on the product packaging. A good performing label on smooth PET will peel off corrugated cartons (Riciclato) or textured HDPE.

Use the Release Liner as a Processing Component.

The release liner helps to hold the label in place while being printed, die-cut and dispensed. If the thickness is not correct, the release force or stiffness is too large, the result is that the web breaks, poor die-cutting or automatic peeling is unstable.

Glassine liners are commonly used as they are smooth, dense and are suitable for high speed converting. The colour of the liner can also aid the operator or sensor in the production process.

Converters who buy label paper in jumbo rolls should verify that the rolls come with the correct liner grammage, release level and width tolerance and are compatible with their die-cutting equipment.

Label and Roll Geometry

Label width is not the only factor to consider when determining printer compatibility. The core, diametro del rotolo, direction of winding, gap and sensor mark should be the same as the printer and applicator.

Confirm:

• Label width and length
• Corner radius
• Gap between labels
• Diametro interno del nucleo
• Diametro esterno massimo
• Labels per roll
• Face in or face out winding
• Sensing (Divario, Notch, black-mark);Black-mark/sensing (Divario, Notch);

The improper construction of a roll can make a roll that is otherwise acceptable for thermal material feed and calibration fail to do so.

Test Le performance of different barcodes in real-life situations.

Not all dark prints are legible barcodes. These factors have an impact on the scan performance: printhead energy, coating sensitivity, printing speed and barcode size.

Feed labels in the desired printer at normal feed speed. Scan them right away and after exposure to the conditions of heat, umidità, abrasion or storage that they are expected to encounter.

Position of barcode on curved packaging and reflective surfaces should be tested where the angle of scanning may vary due to positioning. Labels should also be tested after cartons have been handled, stacked and transported to confirm that the user is getting what they expect.

Specify Jumbo Rolls and Finished Rolls Differently

Typically label converters will buy jumbo rolls for slitting and die cutting and then coating them to the desired format. Their studies should be directed towards web uniformity, adhesive coating, release of the liner, control of the splicing, and roll tension.

Labels are typically sold to end users by finished label rolls which can be fed straight into printers. They should focus on the specifications like roll geometry, label count, printer sensing and packaging protection.

Jinbao's custom-made label sticker jumbo roll comes with a variety of label sticker liners, weights, width and adhesive for conversion needs.

Wet handrails and other surfaces are disinfected by the Complete Label Construction.

Only do not approve white face material. A thermal label is a combination of facestock, rivestimento termico, protective layer, adhesive and release liner and roll format.

Use of the final adhesive, liner size and die-cut size and direction of winding should be used in the approval sample. Conduct testing prior to confirming bulk production on the actual printer and package and application line.

Domande frequenti

Q1. Is there a need to use a ribbon with thermal label paper?

Prints without a ribbon directly from a thermal label paper. Thermal transfer labels are essentially designed to be used with a compatible ribbon to form the print output.

D2. Can top coated thermal paper be washed?

Top coating enhances moisture, oil and abrasion resistance. The performance remains dependent on the coating grade, adhesive and exposure time.

D3. Which glue can be used for frozen foods?

Apply an adhesive that will bond at low temperatures and in freezing temperatures. The normal permanent glue will become brittle or fall off at condensation and freezing temperatures.

D4. Are there thermal label papers that can be used on plastic packaging?

Sì, but be sure to match the surface and curvature of the plastic. It is particularly important for plastics with low surface energies like some PE and PP plastics.

Q5. When ordering thermal label rolls, what needs to be defined?

Give the size of the label, diametro del nucleo, diametro del rotolo, the direction of winding, Divario, adesivo, the environment of application and the liner. There should be packaging surface and also printer model included.
