However, Japanese Patent Laid-Open No. 8-104370 discloses a container in which zeolite is dispersed in a specific layer of a laminate forming the container in order to prevent odor from migrating from the container to the food inside the container. The technology of adding zeolite to any layer of the laminate has not been proposed so far.

Embodiment 1
[0036] Using a 30mmφ twin-screw extruder, LDPE (A) [manufactured by Japan Polyethylene Co., Ltd., LF440HB, MFR: 2.8g / 10 minutes (190°C, load 2160g), density: 0.925g / cm 3 ], calcium stearate S (B) [manufactured by NOF Co., Ltd.], natural mordenite-type zeolite (C) [manufactured by Nitto Powder Chemical Industry Co., Ltd., SP#2300] and ethylene-vinyl acetate copolymer The weight ratio of saponified product (D) [TOSOH Co., Ltd., Melthene H6051, ethylene content: 89 mol%, saponification degree: 100 mol%, MFR: 5.5g / 10min (190°C, load 2160g)] is ( The resin composition of A) / (B) / (C) / (D)=70 / 5 / 10 / 15 ((A) / (D)=82 / 18) was kneaded to produce modified pellets.
[0063] Except that ethylene-vinyl acetate copolymer saponified product (D) is not mixed, and the weight ratio is LDPE (A) / calcium stearate (B) / zeolite (C)=85 / 5 / 10, the same as in Example 1 Evaluation was performed in the same manner, and the results are shown in Table 1.
Embodiment 3
[0065] In addition to using polypropylene [Japan Polychem Co., Ltd., FY6C, MFR: 2.4g / 10 minutes (230°C, load 2160g), density: 0.90g / cm 3 ] except that LDPE (A) was replaced, it evaluated similarly to Example 1, and the result is shown in Table 1.

Abstract
A resin composition to be added in reprocessing recovered laminates containing a saponified ethylene / vinyl acetate copolymer; and a process for production of laminates by use of the composition. Specifically, a resin composition comprising (A) a polyolefin, (B) a metal salt of a higher fatty acid having 12 to 30 carbon atoms, and (C) zeolite; and a process for the production of a laminate which comprises adding the resin composition to a laminate containing a saponified ethylene / vinyl acetate copolymer and subjecting the obtained mixture to reprocessing.
Description
technical field [0001] The present invention relates to a resin composition which can improve various problems occurring during processing by adding it when recycling a laminate containing saponified ethylene-vinyl acetate copolymer to reprocess the laminate. Moreover, this invention relates to the method of manufacturing a laminated body using this resin composition. Background technique [0002] Laminates composed of polyolefins, modified polyolefins (adhesive resins), and ethylene-vinyl acetate copolymer saponified products (hereinafter also referred to as EVOH) are recycled and reprocessed, and can be used in laminates. in manufacture. However, due to the influence of the catalyst contained in the polyolefin, there is a problem that stagnant degradation products derived from EVOH and the like are generated during reprocessing. In addition, when an organic or inorganic colorant is contained in the recycled laminate, there is also a problem of gelation of EVOH due to agg...
