Embodiment 1

[0120] Hereinafter, examples of the expanded bead molded body used in the panel packaging container will be described. In this example, as described below, composite resin expanded particles were produced from the core particles, and an expanded particle molded body was produced using the composite resin expanded particles.

[0121] (1) Preparation of nuclear particles

[0122] As the vinyl resin, linear low-density polyethylene polymerized using a metallocene polymerization catalyst (specifically, "Nipolon-Z HF210K" manufactured by TOSOH Corporation) was prepared. The vinyl resin of this example is hereinafter referred to as "PE-1" as appropriate. MFR (unit: g / 10min), density (unit: kg / m3) of PE-1 at a temperature of 190°C and a load of 2.16kg 3 ), tensile modulus (unit: MPa), and melting point (unit: °C) are shown in Table 1 below. The MFR of PE-1 under the conditions of a temperature of 190° C. and a load of 2.16 kg is a value measured under condition code D based on JIS...

Embodiment 2

[0158] In this example, first, core particles were prepared in the same manner as in Example 1, except that the amount of the vinyl resin (i.e., PE-1) was changed from 8.65 kg to 9 kg, and the amount of the cell regulator masterbatch was changed to 9 kg. Amount changed from 1.35kg to 1kg. Next, composite resin particles were prepared in the same manner as in Example 1, except that 100 g of the core particles were used, a mixed monomer of 85 g of styrene and 15 g of butyl acrylate was used as the first monomer, and 300 g of styrene was used as the second monomer. Two monomers. Then, using the composite resin particles, an expanded particle molded body was produced in the same manner as in Example 1.

Embodiment 3

[0160] In this example, first, core particles were prepared in the same manner as in Example 1, except that the amount of the vinyl resin (i.e., PE-1) was changed from 8.65 kg to 8 kg, and the amount of the cell regulator masterbatch Quantity changed from 1.35kg to 2kg. Next, composite resin particles were prepared in the same manner as in Example 1, except that 53 g of the core particles were used, a mixed monomer of 38 g of styrene and 15 g of butyl acrylate was used as the first monomer, and 394 g of styrene was used as the second monomer. Two monomers. Then, using the composite resin particles, an expanded particle molded body was produced in the same manner as in Example 1.

Abstract

The invention provides a panel packaging container. The panel packaging container has excellent compression rigidity and bending resistant performance and is capable of preventing deformation. The panel packaging container (1) has an accommodating part (10) which can accommodate a plurality of panels (4) that are laminated along the thickness direction. The panel packaging container (1) comprises a molded body, which is made of molding composite resin foamed particles with an apparent density of 40 to 100 kg / m3 in a mould. The composite resin that forms the foamed particle molded body is prepared by dipping 100 parts by weight of ethylene resin in 400 to 900 parts by weight of styrene monomers. For the composite resin, the swelling capacity of the mixed insoluble component composed of the xylene insoluble component in Soxhlet extraction of xylene and the xylene solution containing an acetone insoluble component after Soxhlet extraction in methyl ethyl ketone with a temperature of 23 DEG C is more than 1.25. The bending elasticity of the foamed particle molded body is greater than 18 MPa, the bending rupture energy is more than 150 J / cm2, and the 50% compression stress is greater than 400 kPa.

Description

technical field [0001] The present invention relates to a panel packaging container comprising a foamed particle molded body formed by in-molding composite resin foamed particles. Background technique [0002] In the past, in the packaging of plate-shaped products such as liquid crystal panels and solar power generation panels, propylene-based resins have been used for the reasons that abrasion, cracking, and defects due to pressure damage and friction will not occur, and they can be used many times. The container of the expanded particle shaped body. In recent years, as the panel size has expanded, the package weight has also increased. As a result, in the container containing the foamed particle molded article of the propylene-based resin, the problem of increased deflection in the packaged state arises. If the deflection during packaging is large, when both ends of the packaged container are supported by a transfer machine or the like and lifted, the liquid crystal pane...
