Provided are a polyester film that is usable for protecting a surface of a metal plate of a construction material, a decorative material, an interior material, an electronic product, etc., and a manufacturing method therefor, and a polyester mold product using the same and a manufacturing method therefor, wherein the polyester film has low orientation and low modulus to have excellent moldability.

Polyester film and manufacturing method therefor, and polyester mold product using same and manufacturing method therefor

Provided are a polyester white film and a back sheet for a solar cell module using the same, and in particular, provided is a polyester white film having improved light reflectance.

Back sheet for solar cell module and method for manufacturing the same

Provided is a polyester film having excellent high-temperature dimensional stability. More particularly, provided is a method for producing a polyester film, including: a) extruding and cooling a polyester resin to provide a non-oriented sheet; b) orienting the sheet in the machine direction (MD); c) orienting the MD oriented sheet in the transverse direction (TD); d) heat treating the sheet; and e) carrying out simultaneous relaxation by subjecting the heat treated sheet to MD relaxation at a ratio of 1% or higher, while subjecting it to TD relaxation in a tenter. Provided also is a polyester film obtained by the method.

Polyester film and manufacturing method thereof

The present invention relates to a metalizing film including a polyester-based film layer having a heat-shrinking property, and a use of the metalizing film used as a film label capable of replacing a paper label attached to a glass bottle.

Polyester-based metalizing film

Provided are a film for food packaging, capable of having excellent adhesion with a metal deposition layer and thus retaining moisture barrier property while having superior flexibility, transparency, and biodegradability, and a method for manufacturing the same.

Shrinkable film and method for manufacturing same

Disclosed is a thermo-shrinkable polyester film in which shrinkage uniformity is ensured in a shrinking process thus realizing superior quality of the outer appearance without causing a poorly printed state, reducing the production cost of the shrinking process and improving the productivity.

Thermo-shrinkable polyester film

The present invention relates to a heat-shrinkable polyester-based single-layer film which has superior shrinkability and color, and thus provides aesthetic enhancement to the product to which the film is attached when the film is printed. Therefore, the polyester-based single-layer film of the present invention can be valuably used as a label film as it can replace labels made of paper, and can be easily peeled off by means of hot water, thus contributing to the recycling of bottles.

Heat-shrinkable polyester-based single-layer film

Disclosed is a thermo-shrinkable polyester film having superior thermal shrinkage properties. The thermo-shrinkable polyester film has a strength of 3.5&#x2dc;6.5 kg/mmin a direction perpendicular to a main shrinking direction at an initial elongation less than 10%, an elongation at rupture of 50&#x2dc;700% in a direction perpendicular to a main shrinking direction, a thickness uniformity (&#x394;R) of 4 or less and a shrinkage ratio of 5% or less in a direction perpendicular to a main shrinking direction, thus preventing the rupture thereof in a rolling process and so on and ensuring process stability and productivity.
