Cosmetics and personal care packaging often carries variable information such as batch numbers, manufacturing dates, expiry or best-before dates, serial numbers and machine-readable codes. PTS Technology helps Malaysian manufacturers evaluate BENTSAI thermal inkjet (TIJ) coding options for small-batch work, rework stations and production-line applications.
The correct solution depends on the actual packaging material, surface condition, print area, required message, production method and handling environment. A printer or ink should not be selected from the packaging description alone.
Common Cosmetics and Personal Care Coding Applications
- Batch, lot and internal production identification
- Manufacturing, expiry or best-before dates specified by the customer
- Serial numbers and variable text
- QR codes and other machine-readable data provided by the customer
- Outer-carton and secondary-packaging identification
- Small-batch, sample, rework and supplementary printing
Packaging That May Require Coding
Potential applications include plastic bottles, tubes, jars, caps, flexible pouches, sachets, labels, folding cartons and corrugated shipping boxes. However, two packages that look similar may use different resins, laminates, varnishes or surface treatments. Their print results can therefore be different.
Surface and Ink Compatibility Must Be Tested
Not every surface is suitable for direct TIJ printing. Ink adhesion can vary according to the packaging material, coating, lamination, surface energy, oil or chemical residue, surface treatment and selected ink formulation.
Gloss-coated cartons, varnished boxes, laminated pouches, low-surface-energy plastics and containers carrying oil, silicone, mould-release agent or product residue may produce weak adhesion, slow drying, smudging or easily removable prints. A solvent-based ink is also not guaranteed to adhere to every coated or non-porous surface.
| Surface or condition |
Typical concern |
What to confirm |
| Uncoated paper or carton |
Ink absorption and edge sharpness |
Clarity, contrast and bleed |
| Gloss-coated or varnished carton |
Slow drying or weak adhesion |
Drying time and rub resistance |
| Plastic bottle, jar or cap |
Low surface energy or treatment variation |
Adhesion on the actual production item |
| Laminated pouch or sachet |
Film layer and coating differences |
Smudging, handling and storage behaviour |
| Oily, silicone-contaminated or dusty surface |
Poor ink contact |
Surface cleaning and process control |
Customers should provide actual packaging samples for print testing before choosing the printer and ink. Testing should assess print clarity, drying time, smudging during handling, adhesion after rubbing, print position and behaviour under the intended storage and production conditions.
Handheld or Inline Coding?
| Workflow |
Often considered for |
Important checks |
| Handheld coding |
Samples, small batches, rework, finished cartons and changing locations |
Operator consistency, guides, package shape and access to the print area |
| Inline coding |
Repeated coding on moving products or packages |
Product spacing, sensor position, conveyor stability, print distance and line integration |
PTS Technology can help compare available BENTSAI handheld and industrial options after reviewing the customer’s message, sample, workflow and expected production conditions. Product suitability remains subject to application testing.
Recommended Customer Sample-Test Workflow
- Provide the actual packaging sample: Include every relevant material, coating and colour variation.
- Define the message: Confirm the required text, date format, code size and print location.
- Test the proposed ink and setup: Observe clarity, drying and adhesion under realistic handling conditions.
- Review the result: The customer confirms whether the print meets its internal quality and packaging requirements.
- Approve the production setup: Record the selected ink, position and operating method before routine use.
Information Needed Before a Recommendation
- Actual packaging sample and surface description
- Required message, code type and approximate print area
- Manual, rework or conveyor-based operation
- Expected production volume and product change frequency
- Handling, storage and environmental conditions
- Customer’s acceptance method for adhesion and readability
Frequently Asked Questions
Can a TIJ printer print on every cosmetic packaging surface?
No. Printability and adhesion depend on the material, coating, contamination, surface treatment and ink formulation. The actual packaging should be tested first.
Can coated or varnished cosmetic boxes be printed directly?
Possibly, but the result cannot be assumed. Coatings may reduce ink adhesion or extend drying time, so the actual box must be tested.
Can oily bottles or containers be printed?
Oil, silicone and product residue can interfere with ink contact. Surface condition and cleaning controls should be evaluated before production.
Should a handheld or inline printer be selected?
Handheld printing is often considered for flexible, low-volume or rework tasks. Inline printing is generally considered for repeated coding on a controlled production line. The package and workflow must still be reviewed.
Does PTS Technology confirm packaging or regulatory compliance?
No. PTS Technology supplies product information, available manufacturer documentation and application testing support. Customers are responsible for confirming the information required on their packaging and approving the final production setup.
Important notice: This page provides general product and application information only. PTS Technology does not guarantee compatibility with every packaging surface and does not provide legal, regulatory, quality-system or product-registration advice. Customers must independently verify applicable requirements and approve the final ink, material, message, print position and production method.
