Polystyrene (PS / HIPS) vs Polyethylene Terephthalate (PET) for Face Seal Blister Packaging: Which Sheet Wins in toys and games?

2026-10-02 Plastic News 2 views

Polystyrene (PS / HIPS) and Polyethylene Terephthalate (PET) are the two most quoted sheet materials for face seal blister packaging in toys and games projects. Both run well on standard thermoforming equipment, but they differ in clarity, toughness and sealing.

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 face seal blister packaging 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 cavity depth up to 60 mm; sheet gauge 0.20 to 0.60 mm; transparent, frosted and coloured. Materials most often specified are Polypropylene, Polystyrene, Polyethylene Terephthalate, Recycled PET, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.

In the toys and games sector the decision is usually driven by child safety and presentation, with durability as a secondary requirement. Typical end uses include model kit trays, craft set packs, game inserts.

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
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
Polyvinyl Chloride1.38-1.45 g/cm³40-55 MPa-10°C to 60°C

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

Polystyrene Compared With Polyethylene Terephthalate

Polystyrene grades offer rigid and glossy, while Polyethylene Terephthalate brings excellent barrier to CO2 and moisture. For toys and games service the difference shows up in chemical resistance and in the long term behaviour under load.

  • Polystyrene: HIPS is the default thermoforming sheet for food packaging and appliance liners.
  • Polyethylene Terephthalate: High IV PET resin is the reason a 1.5 L bottle can be light yet hold carbonation pressure.

Both materials can be validated quickly with a small sample run, which is the cheapest way to settle the argument for your own application.

Common Grades and Variants

  • Polyvinyl Chloride based: inherently flame retardant
  • Polystyrene based: rigid and glossy
  • Recycled PET based: lower carbon footprint than virgin resin
  • 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

Each step below has its own control points, and skipping one of them is where most defects start.

  • Die cutting
  • Pressure forming
  • Heat sealing
  • Sheet extrusion

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 Face seal blister packaging Correctly

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

  1. check the corner radius against the sheet gauge
  2. verify recycled content documentation if rPET is used
  3. leave a flat flange for heat sealing
  4. ask for a drop test on the finished pack
  5. confirm the sealing coating matches the card

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 face seal blister packaging?

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 face seal blister packaging 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.

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 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.
