Embodiment approach

[0018] Regarding this foam seat, the following foam seat is illustrated as an example to describe this embodiment: a polymer type antistatic agent, an anionic surfactant, and an anionic surfactant for promoting The polyethylene-based resin composition of the exuded exudation accelerator is extruded and foamed to form a sheet-shaped foam sheet.

[0019] The thickness of the said foam seat|seet is 0.15-0.50 mm, Preferably it is 0.20-0.45 mm. Since the said foam seat|seet has a thickness of 0.15 mm or more, there exists an advantage that cushioning property becomes excellent. Moreover, since the said foam seat|seet has a thickness of 0.50 mm or less, space can be saved at the time of conveyance of glass, As a result, there exists an advantage that conveyance efficiency improves.

[0020] In addition, about the thickness of a foam seat|seet, 50 points were measured every 5 cm in the width direction about the arbitrary point, and the arithmetic mean value of the measured value was...

Embodiment 1

[0214] Compared to low-density polyethylene resin manufactured by Nippon Polyethylene Co., Ltd. (trade name: "LF580", density: 929kg / m 3 , MFR=4.0g / 10min) 100 parts by mass, the polymer antistatic agent manufactured by Sanyo Chemical Co., Ltd. (polyether-polypropylene block copolymer, trade name: "PELESTAT300", crystallization temperature: 85.4 ° C, MFR=30g / 10min) with 6 parts by mass, the product name "CHEMISTAT3033" manufactured by Sanyo Chemical Industry Co., Ltd. (containing 90 mass% or more of carbon number 12-16 sodium alkyl sulfonate as an anionic surfactant. Softening point 70 °C) was mixed with 0.5 parts by mass and 0.3 parts by weight of a cell regulator masterbatch manufactured by Sankyo Kasei Co., Ltd. (masterbatch containing azodicarbonamide: trade name "CELLMIC MB1023") to obtain The compound is supplied to the first extruder of the series extruder (barrel diameter: ), melt-kneading was carried out so that the highest temperature in the extruder was 210°C.

Embodiment 2

[0219] The amount of mixed butane as a foaming agent is set to 13 parts by mass relative to 100 parts by mass of the aforementioned low-density polyethylene resin, and the amount of the cell regulator masterbatch is set to be 13 parts by mass relative to 100 parts by mass of the aforementioned low-density polyethylene resin It was 0.4 mass parts, and except having made the resin temperature at the time of extrusion into 114.7 degreeC, it carried out similarly to Example 1, and obtained the roll-shaped foam seat|seet.

Abstract

The invention provides a polyethylene resin foam sheet for cardboards, wherein the polyethylene resin foam sheet is excellent in buffer property and the glass is not easy to slide. The polyethylene resin foam sheet for cardboards is characterized in that the thickness, the basis weight, the surface resistivity, the arithmetic mean of the surface roughness, the maximal height of the surface roughness and the average length of the contour unit of the surface roughness thereof are respectively 0.15-0.50 mm, 15-50 g / m2, 109-1013 omega, 25-50 mum, 120-250 mum, and 200-600 mum. The result of dividing the thickness by the maximal height of the surface roughness is 1.3-3.

Description

technical field [0001] The present invention relates to a polyethylene-based resin foam sheet for a backing paper used as a backing paper of a glass plate. Background technique [0002] Since the foamed polyethylene-based resin sheet is soft and has excellent cushioning properties, it can be used as packaging materials for electronic components and home appliances, as mounts for glass, and the like. (For example, Patent Documents 1, 2) [0003] For example, glass substrates for flat panel displays such as liquid crystal displays and plasma displays are supplied from glass makers to display makers in a state where polyolefin-based resin foam sheets are interposed therebetween.
