PEN (Poly(ethylene 2,6-naphthalate) is a polyester with good barrier properties (even better than Polyethylene terephthalate). Because it provides a very good oxygen barrier, it is particularly well-suited for bottling beverages that are susceptible to oxidation, such as beer. It is also used in making high performance sailcloth.
It is important to note that food contact PEN materials and articles are also obliged to comply with the existing specifications for general plastics as follows:
Food contact material | Index | Requirement | Effective date |
Polyethylene Naphthalene (PEN) | Evaporation residue | ≤ 30 μg/ml | 8 December 2016 |
Specific migration of germanium | ≤ 0.1 μg/ml | ||
Cadmium content | ≤ 100 μg/ml | In force | |
Consumption of potassium permanganate | ≤ 10 μg/ml | ||
Lead content | ≤ 100 μg/ml | ||
Migration of heavy metals (as lead) | ≤ 1 μg/ml |

Japan intends to formulate PEN food contact products specifications and standards—C&K Testing in Feb.
