A film for an electronic substrate according to an embodiment has a moisture-absorption rate of less than 0.3% of the initial weight when immersed in water for 24 hours, and thus is less susceptible than existing films for electronic substrates are to changes in dimension or degradation in electrical characteristics caused by containing moisture according to changes in temperature and humidity. Also, the film for an electronic substrate is equal or superior to existing films in terms of flexibility and physicochemical characteristics, and thus may be applied to the manufacture of laminates with a conductive film such as FCCL and electronic substrates such as FPCB to improve processability, durability, transmission capacity, etc.

A biodegradable film is prepared from a composition that includes a copolyester obtained by extrusion reaction of a branched aliphatic-aromatic copolyester derived from monomer a, monomer b, monomer c and monomer d with an organic peroxide. The film can be completely degraded into small molecular products such as carbon dioxide, water and the like under natural or composting conditions. Moreover, the film can be prepared having a thickness of 4-50 μm as required, and its mechanical properties can reach the same level as or even better than those of LDPE film.

The invention relates to a preform for producing a plastic container in a blow moulding method, comprising an elongated, preform body, which is formed so as to be closed at the one longitudinal end thereof and, at the other longitudinal end thereof, has a neck section having a pouring opening. The preform is produced from recycled PET and aliphatic furanoate, wherein the recycled PET has a maximum of 2.5 wt % of isophthalic acid and diethylene glycol, wherein the proportion of isophthalic acid is no higher than 2.0 wt %, and the proportion of diethylene glycol is no higher than 2.0 wt %, wherein all the percentages by weight are based on the total weight of the preform. Turbidity of the preform, measured in accordance with ASTM D I 003-00, is less than 5%, as a result of the admixture of the aliphatic furanoate.
