Title:
AGRICULTURAL LAMINATED FILM
Document Type and Number:
Japanese Patent JP2002000085
Kind Code:
A
Abstract:

To provide an agricultural film excellent in various properties including transparency and film formation stability and having thermal insulation and antifogging sustainability.

This agricultural laminated film is composed of a polyethylene- based resin composition layer based on a copolymer of ethylene and a 3-18C α-olefin and satisfying all of the four physical properties described below and a vinyl acetate-based resin composition layer comprising 100 pts.wt. of an ethylene-vinyl acetate copolymer 2.0-30 wt.% in vinyl acetate content and 1-20 pt(s).wt. of inorganic compound(s) having at least one kind of atom among Mg, Ca, Al, Li and Si; wherein the four physical properties are as follows: in the TREF(temperature rising elution fraction) elution curve of the polyethylene-based resin composition, the elution peak temperature for low- crystalline components is 65-92°C, the ratio H/M is ≥20 (H is the peak height for the low-crystalline components, and M is the height of the minimum valley between the low-crystalline component peak height and high-crystalline component peak height), the proportion of the area corresponding to the elution peak temperature or lower for the low-crystalline components to the total area corresponding to the TREF elution curve, and MFR is 0.1-10 g/10 min.
