Handling, Storage and Service Life of PS / HIPS Thermoformed Point of Sale Display Trays in electronics and electrical

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 printed graphics and logo embossing; gauge 0.50 to 2.00 mm; counter and shelf formats. Materials most often specified are Recycled PET, Polyethylene Terephthalate, Polypropylene, Polyvinyl Chloride, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.

In the electronics and electrical sector the decision is usually driven by ESD protection and dimensional accuracy, with cleanliness as a secondary requirement. Typical end uses include connector carriers, component trays, device inserts.

Key Material Properties

Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.

MaterialDensityTensile strengthService temperature
Polyvinyl Chloride1.38-1.45 g/cm³40-55 MPa-10°C to 60°C
Polyethylene Terephthalate1.35-1.40 g/cm³50-70 MPa-40°C to 70°C
Polypropylene0.90-0.91 g/cm³25-40 MPa-10°C to 100°C

Polystyrene is frequently the default selection here: HIPS is the default thermoforming sheet for food packaging and appliance liners.

Installation and Care

Build these steps into your standard work instruction.

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

With correct specification and installation, service life in typical indoor conditions exceeds ten years.

Common Grades and Variants

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

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

The route below is the one most factories use for this type of part.

  • Assembly
  • Pressure forming
  • Vacuum forming
  • Die cutting

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

Use this checklist when comparing two or three supplier quotations.

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

Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.

Frequently Asked Questions

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.

What is the minimum order quantity for thermoformed point of sale display trays?

For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.

Can you produce thermoformed point of sale display trays in Polystyrene?

Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.

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.
