What is APET rPET?

APET rPET is APET in the rPET grade — choose for recycled-content targets and cost; expect slight haze/tint and lower ductility batch-to-batch. APET rPET has a yield strength of 51 MPa (7.4 ksi) and a tensile strength of 52 MPa (7.54 ksi) — stronger than 54% of polymer grades. Elongation at break is 150% and the elastic modulus is 2.3 GPa (0.326 Msi). APET rPET has a density of 1.34 g/cm³ (0.0482 lb/in³), heavier than 74% of polymer grades. Its glass-transition temperature is 78°C (172 °F).

Working with APET rPET

Is APET easy to machine?

Die-cuts, steel-rule punches and CNC routers work well with sharp positive-rake tools and air blast; avoid heat build-up which locally crystallizes and whitens the cut edge.

Can APET be welded?

Excellent heat, impulse, HF and ultrasonic sealing; solvent bonding is poor, so use hot-melt/PSA or mechanical snap-fit for secondary joining.

Can APET be formed, bent or molded?

Dry sheet 4 h at 60–70 °C before extrusion/regrind; thermoform at 120–160 °C sheet temperature with fast quench moulds (10–25 °C) to keep the part amorphous and clear.

What surface finishes work on APET?

Accepts corona-treated flexo/screen/UV offset printing, hot stamping and in-mould labels; no plating, and hot alkaline cleaning must be avoided (hydrolysis).

APET rPET — frequently asked

What is APET rPET used for?

APET rPET is typically used for thermoformed clamshell packaging, blister packs, food trays and protective covers. In short: clear thermoforming PET sheet; amorphous, not ovenable; food-contact packaging sheet.

What is the yield strength of APET rPET?

APET rPET has a typical yield strength of 51 MPa (7.4 ksi) and a tensile strength of 52 MPa (7.54 ksi) — stronger than 54% of polymer grades. Strength varies by condition: see the 6 listed tempers.

Is APET rPET easy to machine?

Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Die-cuts, steel-rule punches and CNC routers work well with sharp positive-rake tools and air blast; avoid heat build-up which locally crystallizes and whitens the cut edge.

Can APET rPET be welded?

With care — weldability is rated fair (40/100). Excellent heat, impulse, HF and ultrasonic sealing; solvent bonding is poor, so use hot-melt/PSA or mechanical snap-fit for secondary joining.

What surface finishes work on APET rPET?

Accepts corona-treated flexo/screen/UV offset printing, hot stamping and in-mould labels; no plating, and hot alkaline cleaning must be avoided (hydrolysis).

Can APET rPET be formed, bent or molded?

Dry sheet 4 h at 60–70 °C before extrusion/regrind; thermoform at 120–160 °C sheet temperature with fast quench moulds (10–25 °C) to keep the part amorphous and clear.

What is the maximum service temperature of APET rPET?

APET rPET is rated for continuous use to about 65°C (149 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
