RPET Trapped Blister Carded Packaging Specifications for retail and merchandising: Gauge and Tolerances

2026-10-02 Plastic News 2 views

Specification sheets for trapped blister carded packaging are full of abbreviations. This guide translates sheet gauge, cavity layout and trim tolerance into decisions you can make.

This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.

Product Overview

This category covers a family of products rather than a single item. In practice a buyer defines trapped blister carded 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 standard pegboard hole patterns; card sizes to 250 x 400 mm; gauge 0.25 to 0.50 mm. Materials most often specified are Polyethylene Terephthalate, Polystyrene, Polyvinyl Chloride, Recycled PET, 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, counter displays, pegboard 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
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
Polystyrene1.04-1.06 g/cm³30-50 MPa-20°C to 70°C

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

Dimensions, Grades and Tolerances

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

  • card sizes to 250 x 400 mm
  • single or twin cavity
  • anti-static grades for electronics
  • standard pegboard hole patterns
  • gauge 0.25 to 0.50 mm

When you read a supplier quotation, check that the dimension, the resin grade, the colour reference and the tolerance class are all stated. A quotation that only gives a price per piece is not comparable between suppliers.

Common Grades and Variants

  • Polyethylene Terephthalate based: excellent barrier to CO2 and moisture
  • Polystyrene based: rigid and glossy
  • Recycled PET based: lower carbon footprint than virgin resin
  • Polyvinyl Chloride based: inherently flame retardant

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.

  • Vacuum forming
  • Hanging hole punching
  • Heat sealing
  • 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 Trapped blister carded packaging Correctly

These are the criteria that actually predict whether the part will perform in service.

  1. confirm the peg hole pattern required by the retailer
  2. validate seal strength with a peel test
  3. check the card flatness after sealing
  4. use anti-static material for electronics
  5. match the heat seal coating to the card stock

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

Frequently Asked Questions

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.

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 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.

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.

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.
