PET?PP?PC?Polystyrene? A picture to understand the various terms of polymer used in printing.

Whenever we discuss printing materials with the printer, all sorts of "Poly's" come up. Do you have a lot of questions? What are they talking about when they speak of Tetoron, Polystyrene, PolyGold, PolySilver...? What are the differences in the characteristics of these materials? Holo Solution Inc. has compiled a list of the various types of Lon's and the various P's that are not Lon's.

PET?PP?PC?Polystyrene? A picture to understand the various terms of polymer used in printing.

The various types of Poly's used in printing materials


|Poly- name|

PET (polyethylene terephthalate)

Polyester, Mylor, Peto


Temperature resistance range: -20-120℃; Melting point: 260 degrees

High density (1.38) and stiffness

Good weather resistance


Lightly shaken, brittle sound

Does not stretch or tear easily

Flame is yellow with fragrance

Flames are white when blown out

Mostly made of tamper evident material


|Poly- name|

PVC (polyvinyl chloride)


Temperature resistance range: 60 degrees

Hard density 1.4, soft 1.2

Good weather resistance

A common material for shrink film.


Hard PVC is easily confused with PET.

Soft PVC is more ductile.

Smells badly

The flame is green with a sour smell.

The flame is black when blown out.


|Poly- name|

Electroplated PET, PolyGold, PolySilver

PolyGold(PolySilver)-Bright Polyester


PolySilver is a PET or PVC plated aluminum

Similar to the original material PET or PVC

PolyGold is dyed yellow and then plated with aluminum

PVC is less temperature resistant than PET

PVC is easier to print and attach than PET.


Similar to PET or PVC.

Variant plastic coating

|Poly- name|

PolyGold (PolySilver) with a surface treatment

Similar in nature to PET or PVC.

|Matte PolyGold (PolySilver) |

It is a matte PolyGold (PolySilver) material

|Silky PolySilver|

Hairline Polystyrene

PolySilver material with a brushed finish

Transparent Polystyrene

|Poly- name|

Transparent PET, transparent stickers

There are also transparent laminates made of Polystyrene!


The same as Tetoron

Stiffer than PP (not suitable for bending)

More transparent and brighter than PP

More scratch resistant than PP

Easier to print and adhere than PP


Compared to Tetoron

The various types of “P’s” used in printing materials


|Poly- name|

Polypropylene, bright (fog) P

OPP is unidirectional oriented stretch PP

POPP is bi-directional stretch film


Temperature resistance range: about 70 degrees

Often used as a laminate for ink and moisture protection

Printing does not adhere easily

Easily scratched than Tetoron


Softer and easier to tear than Polyester.

Smells like candles after burning


|Poly- name|



Temperature resistance range: about 60-70 degrees

Soft material

Mostly used for plastic bags and lamination inside laminated bags.


Can be easily torn and stretched by hand.

Tearing the parallel side fine and smooth

No odor or candle smell when burned

PE powder is an important component of fragile stickers.

Synthetic PP

|Poly- name|

Synthetic polypropylene

Sometimes abbreviated as synthetic paper

But there are many kinds of synthetic paper


Temperature resistance range: about -20-80 degrees

More water and moisture resistant than paper

Easier to print and attach than Tetoron

Can be used instead of PVC


Muffled sound when shaken lightly

Can be torn off by hand with irregular jagged shape.

PP Sythetic Paper

|Poly- name|

PEPA®, Polypropylene + Acrylic film


Temperature resistance range: about 80 degrees

Water-proof and moisture-proof

Better opacity than synthetic PP

Multi-layer coating on the surface

Print adhesion must be observed


Muffled sound when shaken lightly

Easy to peel off with a single stroke

The surface coating can be removed with a fingernail

or a strong object.


|Poly- name|



Not resistant to chemical corrosion

Easily scratched, soft and impact resistant

Surface is often embossed or matte

Can be stamped, but yellowing will occur if engraved

Less than 100um, often compared to PET

Larger than 100um, often compared with PMMA


Flammable with aroma (phenol)


|Poly- name|

Polymethyl methacrylate




Good hardness

Scratch and abrasion resistant, not impact resistant and easily cracked

Can be laser cut and engraved

High optical transparency


More resistant to scratches than PC

Usually thicker (>0.64mm)
