Handling, Storage and Service Life of rPET Thermoformed Point of Sale Display Trays in retail and merchandising

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; multi tier and stepped designs; counter and shelf formats. Materials most often specified are Polyethylene Terephthalate, Recycled PET, Polyvinyl Chloride, Polypropylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.

In the retail and merchandising sector the decision is usually driven by shelf presentation and print quality, with stack strength as a secondary requirement. Typical end uses include dump bins, shelf trays, promotional packs.

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
Polystyrene1.04-1.06 g/cm³30-50 MPa-20°C to 70°C
Polyethylene Terephthalate1.35-1.40 g/cm³50-70 MPa-40°C to 70°C

Recycled PET is frequently the default selection here: Food-grade rPET requires a recognised recycling process plus solid-state polycondensation.

Installation and Care

Build these steps into your standard work instruction.

  1. Clean with mild detergent and a soft cloth; avoid solvents unless the data sheet allows them.
  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. Re-check torque or alignment after the first month of service.
  5. Use fixings that allow for thermal expansion; do not clamp rigidly.

Outdoor service life depends mainly on the UV stabiliser package and the colour.

Common Grades and Variants

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

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.

  • Die cutting
  • Assembly
  • Vacuum forming
  • Pressure forming

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

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

Frequently Asked Questions

Do you offer samples?

Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.

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.

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 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.
