Escolhendo um fornecedor atacadista confiável de papel térmico

While the lowest price per roll might not be the lowest operating cost. Many factors can detract from the useful value of a wholesale order, such as short rolls, oversized cores, uneven coatings, too much paper dust and feeble export cartons.

So importers, converters and distributors are advised to consider the output of the Wholesale Thermal Paper Roll Suppliers based on measurable output and not just quoted roll size or container price.

There are three elements to the correct evaluation: paper performance, converting accuracy and batch consistency, documentation and supply continuity.

Choose between Jumbo Rolls and Finished Rolls.

A converter is typically a purchaser of jumbo rolls and manufacturer of local POS, ATM or ticket rolls. Finished rolls are typically needed by retail distributors and chain-store buyers, which can then go straight to warehouses or into brand sales.

Jin Bao Brother offers quality thermal paper jumbo rolls as well as finished thermal paper rolls.

Jumbo rolls offer:

• Flexible local converting
• Fewer production changeovers
• Custom finished dimensions
• Reduce packaging volume per square foot of paper.

Finished rolls decrease converting work, but they need more attention with regard to roll length, Núcleo, winding and individual packaging.

Em vez de, compare the size of the usable paper versus the size of the nominal Rolar of paper.

Different quantities of paper can be in two rolls of paper that are the same diameter. Actual roll length is dependent on paper thickness, Peso, winding tension and core diameter.

Verify:

• Paper width
• Peso
• Caliper
• Total roll length
• Inside and outside diameter of cores.
• Roll outer diameter
• Net paper weight
• Winding tightness
• End-of-roll attachment

If the core is oversized then a roll will be larger but not have more paper in it to be used. Too much winding tension can result in curling, too little can result in telescoping when being transported.

When comparing costs, use the price per usable meter, square meter or net paper weight; not the price per roll.

Prática consistência of test thermal coating.

Thermal coating should be stable and consistent in response over the entire width of the paper and the entire roll. Variable coating can result in low text density, dark backgrounds, poor bar code quality, and/or increased printer-energy usage.

As part of the wholesale evaluation:

• Escuridão de impressão
• Background whiteness
• Barcode scanning and QR-codes scanning.
• Cross-width uniformity
• When printing at normal printer speed.
• Estabilidade da imagem
• Coating residue
• Printhead contamination

Jinbao thermal paper jumbo rolls are available in a variety of different widths, grammages and coating options that can be customized for commercial converting and distribution.

Be sure that a number of rolls, taken from various points in the production line, are used, rather than any one roll prepared by the supplier.

Determine the quality of slitting and winding.

Completed rolls need to feed reliably in high duty printers in the point-of-sale (PDV), Caixa automático, and kiosk applications.

Inspect:

• Width accuracy
• Clean slit edges
• Roll hardness
• Side alignment
• Telescopismo
• Loose paper dust
• Core position
• End-of-roll bonding
• Splices or joints

Loose fibres and rough edges can lead to more printer contamination. If winding is not done properly, it can rub the roll against the printer compartment causing uneven feed.

Other factors that affect downstream yield that converters should consider for jumbo rolls are web tension and roll edge damage and splice locations.

Control Batch-to-Batch Variation

Later orders of containers may exhibit color, thickness or imaging response differences from a first sample that performs well.

Good suppliers should manage:

• Fonte do artigo base
• Coating formulation
• Peso
• Moisture level
• Brancura
• Sensibilidade térmica
• Roll dimensions
• Packaging materials

Jinbao claims to have a manufacturing system consisting of thermal coating, Corte, rewinding and finished product packages. It's Perfil da empresa states that it has been running its “Integrated Factory Supply” system since 1992.

Buyers are advised to keep the approved samples and make comparisons with successive samples on the same printers and with the same test files.

Align Chemistry to the Target Market

All markets and applications have different chemical needs. Where BPA free or BPA/BPS free or phenol free is specified, this should be set out explicitly and there should be appropriate reports.

Possible documents include:

• ISO 9001 Certificado
• ISO 14001 Certificado
• FSC documentation
• BPA test report or BPS test report.
• RoHS documentation
• REACH-related documentation
• SGS test report

Management-system certificate does not guarantee the performance or chemistry of each paper grade. The report must specify the test substance, and be valid for the product provided.

Jinbao specifies its certifications and standards, such as ISO, FSC, Livre de BPA, RoHS, SGS related and TUV related certifications.

Discuss Embalagem as a part of Product Quality

International transport (humidade, calor, compression and carton movement) can cause damage to thermal paper.

The following should be controlled in wholesale packaging:

• Inner moisture protection
• Rolls per carton
• Carton strength
• Pallet arrangement
• Roll orientation
• Carton labeling
• Batch traceability
• Container moisture protection

After production, the rolls should not be bent due to the stacking of cartons. The end protection and pallet/cradle support must be adequate for jumbo rolls.

Private-label wraps, printed boxes or barcode-marked cartons which can enter the retail distributor's warehouse without repacking may also be required for retail distributors.

Total Landed and Operating Cost (TL)

The comparison should include more than the factory price – it should be realistic.

Considere:

• Paper per roll that can be used:
• Costs for sampling and inspection
• Sea/land transport.
• Import duties
• Damaged cartons
• Repacking labor
• Printer cleaning
• Reprints
• Reclamações dos clientes
• Inventory holding
• Emergency replenishment

If a slightly higher price roll can offer a greater amount of usable paper and fewer jams and fewer rejections, the cost may be less.

Verify Abastecimento Continuity

The wholesale supply should be consistent after the initial order. Buyers should evaluate sourcing of raw material, Capacidade de produção, consistency of lead time and address quality issues.

Useful controls include:

• The following backup paper grades are approved
• Identificação por lotes
• Retained production samples
• Change-notification procedures
• Corrective-action records
• Reorder lead-time tracking
• Forecast-based capacity planning

The change of base paper, coating or core construction by a supplier, without evaluation of its impact on printing and converting, should not be allowed.

Final Supplier Check

These parameters will be maintained as constant as possible from order to order: Usable length, Uniformidade do revestimento, accuracy of slitting, cleanliness of paper, chemical documentation and export packaging.

Jin Bao Brother provides thermal coating, jumbo-roll supply, finished-roll converting and OEM packaging and bulk export. Samples to be tested in the Buyer's printers and or converting line prior to the Specification being the accepted standard.

Perguntas Freqüentes

Q1. What is better to purchase for wholesalers, jumbo rolls or finished thermal rolls?

Often, jumbo rolls are more useful to converters and finished rolls are more useful to distributors and chain buyers. This depends on the local ability to convert and/or the packaging needs.

Q2. How should the buyers compare the price of the thermal rolls?

Compare on the cost per usable meter, square meter or net paper weight. The diameter of the roll alone is not indicative since the length is dependent on the size of the core and the thickness of the paper.

Q3. What is the reason of uneven printing on thermal paper?

This could be due to uneven coating, moisture levels, roughness or inappropriate printer settings. Samples should be taken from various production rolls and tested.

Q4. What are some possible certifications needed?

These can be ISO-, FSC-, BPA/BPS-tested, to RoHS, REACH or SGS. The relevant documents vary depending on the product and the country that it will be exported to.

Q5. Sim, Jin Bao Brother offers custom wholesale rolls.

Sim. Jin Bao Brother can provide jumbo or finished thermal paper roll with different custom widths, Comprimentos, Pesos, cores and coating as well as OEM packaging.
