Handling, Storage and Service Life of PP Thermoformed Point of Sale Display Trays in cosmetics and personal care

2026-10-02 Plastic News 0 views

Correct handling and storage protect the performance of thermoformed point of sale display trays from the factory to the packing line. This guide covers stacking, climate, static and inspection.

The notes below come from day to day production and export work with overseas buyers.

Product Overview

This category covers a family of products rather than a single item. In practice a buyer defines thermoformed point of sale display trays by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include stackable for transport; printed graphics and logo embossing; gauge 0.50 to 2.00 mm. Materials most often specified are Polyethylene Terephthalate, Polystyrene, Polypropylene, Polyvinyl Chloride, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.

In the cosmetics and personal care sector the decision is usually driven by product compatibility and optical clarity, with print quality as a secondary requirement. Typical end uses include gift set inserts, razor packs, mascara blisters.

Key Material Properties

These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.

MaterialDensityTensile strengthService temperature
Polyethylene Terephthalate1.35-1.40 g/cm³50-70 MPa-40°C to 70°C
Polyvinyl Chloride1.38-1.45 g/cm³40-55 MPa-10°C to 60°C
Recycled PET1.35-1.40 g/cm³45-65 MPa-40°C to 70°C

Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.

Installation and Care

Build these steps into your standard work instruction.

  1. Acclimatise the material at the installation temperature for at least 24 hours.
  2. Inspect every part on arrival and record the batch number.
  3. Clean with mild detergent and a soft cloth; avoid solvents unless the data sheet allows them.
  4. Re-check torque or alignment after the first month of service.
  5. Use fixings that allow for thermal expansion; do not clamp rigidly.

Keep a small stock of spares from the same production lot to avoid colour mismatch later.

Common Grades and Variants

  • Polyvinyl Chloride based: inherently flame retardant
  • Polypropylene based: lowest density among commodity plastics
  • Polyethylene Terephthalate based: excellent barrier to CO2 and moisture
  • Recycled PET based: lower carbon footprint than virgin resin

Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.

Processing and Finishing Options

Processing method drives both cost and performance, so it should be fixed early in the design.

  • Pressure forming
  • Vacuum forming
  • Die cutting
  • Assembly

Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.

How to Specify Thermoformed point of sale display trays Correctly

Work through these points in order and most specification mistakes disappear.

  1. design for flat packing to cut freight
  2. validate print adhesion and abrasion
  3. confirm the display location and lighting conditions
  4. use one colour reference for the whole campaign
  5. check stack strength for the loaded display

Frequently Asked Questions

What tolerance can be achieved?

Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.

How do you control colour consistency?

Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.

What packing and shipping options are available?

Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.

How long does tooling and sampling take?

A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.

Which certifications can you provide?

We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.

Conclusion

If you are planning a new cosmetics and personal care project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
