CARALYAN Y/YA2 FILM

Product Information

Outline

This film uses HDPE as its base material, and is extremely easy to cut in straight lines horizontally (TD direction). We have established a technology enabling this film to be cut in straight lines by drawing it in the lateral (TD) direction. It is used in a wide range of applications where a material that cuts cleanly is required, such as foods and tape base materials.

Characteristics

  • It has an excellent ability to cut cleanly in straight lines in the horizontal direction. Such ability is used by laminating with films including aluminum foil and NY, PET, OPP films.
  • It erects straight up thanks to its strength in the horizontal (TD) direction.
  • It is humidity and impact resistant, and has excellent tensile strength and elongation.
  • Extruded lamination and dry lamination are possible.
  • This film has suited the food hygiene standard of Japan.(Notification No. 370, 1959)

Uses

・Food packaging films, tape backing, medical wrappings films, etc..

*1: Measured after 10 minutes of free shrinkage in Geer oven measurement temperature atmosphere
(DENKA method: Unique measurement method of DENKA based on JIS K-7128)
*2: Tear force when torn in Autograph (see JIS K-7128)
*3: Tear strength as tear force when torn in Autograph divided by film thickness (see JIS K-7128)
*4: Straightness of cut when torn at right angle in Autograph

Measurement method for ease of tearing
  • Caralyan Y that has been stored in an isothermal room (23±2 ℃, 50±5% humidity) for 1 day is cut in the TD direction 50 x 150 mm, and a slit is inserted at 75 mm in the center.
  • The vertical chuck of a tensile strength tester is tightened so that either 25 mm-wide side of the slit reaches 180℃.
  • The edges of the film are fixed to a post with adhesive tape.
  • The tear force and tear strength are calculated at each tear distance. (n = 5,200 mm/min) Note: range of 10–70 mm (10 mm intervals)
Measurement method for cut straightness
  • Caralyan Y that has been stored in an isothermal room (23±2 ℃, 50±5% humidity) for 1 day is cut in the TD direction 50 x 300 mm, and a slit is inserted at 100 mm in the center.
  • The vertical chuck of a tensile strength tester is tightened so that either 25 mm-wide side of the slit reaches 90℃.
  • The width from the tear is measured at each tear distance. (n = 5,200 mm/min) Note: range of 50–150 mm (50 mm intervals)
