A film stack comprises an oriented first layer comprising polyvinyl alcohol disposed on an oriented second layer comprising naphthalene dicarboxylate containing copolyester resin. The oriented second layer has in-plane birefringence Δnxy<0.02.

An encapsulated tubular cable with a colorized identification strap includes armored protection ducts and an encapsulation protection layer. A hollow passage is formed in the center of the duct body after each armored protection duct is formed. A wire cable, an optical fiber, or an oil duct is placed in the hollow passage. The encapsulation protection layer wraps the armored protection ducts. A plurality of armored protection ducts are arranged in one encapsulated protection layer. A peripheral edge of each armored protection duct is correspondingly provided with at least one colorized identification strap group. The encapsulation protection layer improves the corrosion resistance of the encapsulated duct cable; the colorized identification straps are provided at the thinnest positions of the encapsulation protection layer to facilitate tearing and encapsulation; and each colorized identification strap has a respective color identifier, which is convenient for distinguishing objects in each hollow passage during use.

The invention relates to a cable comprising layer(s), which layer(s), is/are obtained from a polymer composition, wherein the polymer composition comprises a polyethylene and a crosslinking agent, wherein the polymer composition contains a total amount of vinyl groups which is B vinyl groups per 1000 carbon atoms, and B.sub.1≤B, wherein B.sub.1 is 0.88, when measured prior to crosslinking according to method ASTM D6248-98; and wherein the crosslinking agent is present in an amount which is Z wt %, prior to crosslinking, based on the total amount (100 wt %) of the polymer composition, and Z≤Z.sub.2, wherein Z.sub.2 is 0.60, the cable, e.g. being a power cable, and processes for producing the cable; the cable useful in different end applications, such as wire and cable (W&C) applications.
