Window Coverings



Covered windows on envelopes are important because they ensure envelopes are addressed to the proper person or business, that contents are secure and private, and that envelopes run through the inserting process quickly and without failure.

Envelope window coverings are available in several thicknesses. This is an excellent way to promote source reduction. In fact, the thinnest gauge for envelope window coverings has decreased by 19% over the past 15 years.

The vast majority of window coverings are derived from plastic or petroleum sources.

Window film manufacturers are committed to minimizing the impact on the environment and are producing smaller and thinner windows for envelopes to reduce plastic consumption. In today’s market, four types of window coverings are used:



1. Polystyrene: a plastic film designed specifically for the needs of high speed envelope production;

2. Cellulose based films, such as: glassine and acetate films;

3. PLA: a new film derived from corn; and

4. Other plastic films used for specific, non-standard applications.



Petroleum Consumption in America
0.0002% of all petroleum in the U.S. is used to make polystyrene film for envelope window coverings, all of which is recyclable.

Take a look at where the other 99.998% of petroleum is used in America.

80.00% fuels
17.20% asphalt, road oil and other lubricants
2.60% all plastics
.002% all polystyrenes

Polystyrene pellets are melted and made into film. Manufacturing scrap (start-up waste and edge trim waste) is re-processed into usable film or sold to other plastic processors.

No film in the manufacturing process is sent to a landfill.
