Description

一种特亮特硬专用制袋膜
技术领域
本发明涉及一种制袋膜，尤其涉及一种特亮特硬专用制袋膜。
背景技术
传统CPP制袋膜，手感软，透明性一般，做成的成品包装袋，袋不平整，亮度一般，袋质软不挺硬。但是随着人们对包装袋要求的提高，对膜的硬度，透明度要求越来越高；而且在生产中，降低膜的热封温度，使做好的袋平整、亮度高、袋型挺、硬度大，既能满足使用者的需求，又能降低生产者的费用，对于制袋膜就需要一种新的制备方法。
发明内容
本发明的目的在于解决当前技术中存在的问题，提供一种特亮特硬专用制袋膜。
为达到上述目的，本发明所采用的技术手段是：一种特亮特硬专用制袋膜，由流延机三层共挤而成，具有复合在一起的外层、中层和内层，其中内层采用三元无规聚丙烯为基底和茂金属低密度聚乙烯、开口剂按照40：4：1的比例混合；所述中层采用高抗冲拉丝聚丙烯和成核剂按照10：1的比例混合；所述外层材料采用高抗冲拉丝聚丙烯；挤出速度内：中：外速度是：26%: 37%：37%。
进一步的，所述三元无规聚丙烯采用TF400树脂，茂金属低密度聚乙烯采用SP1520树脂。
进一步的，所述高抗冲拉丝聚丙烯采用纯L5E89树脂。
本发明的有益效果在于：内层添加开口剂，有效防止薄膜粘连，做成的成品包装袋保持良好的开口性，内层加茂金属SP1520，提升膜的热封强度及抗污染热封性能，解决产品在包装粉体及液体类内容物时热封不良的问题；中层添加成核剂，有效提升薄膜的挺度和刚度，增加成品的硬度，使成品袋拥有更好的直立效果，放置于柜台展示效果佳；增加内层的原料流量，有效降低膜的热封温度,提升膜的强度、拉力，有效降低膜的起封温度，制袋时采用较低的温度及热封时间，极大提升制袋的产能和效率，降低废品率；生产出的成品透明性极好，满足客户对产品的高透明要求；薄膜在生产工艺上使用的树脂均是阻隔性能好的原材料，提高制袋膜的阻隔性和密闭性，从而提高膜的各项指标，防漏气，使食品的保香性更好，提高食品的保质时间。
具体实施方式
一种特亮特硬专用制袋膜，由流延机三层共挤而成，具有复合在一起的外层、中层和内层，其中内层采用三元无规聚丙烯为基底和茂金属低密度聚乙烯、开口剂混合，添加量为三元无规聚丙烯100kg、茂金属低密度聚乙烯10kg、开口剂2.5kg；所述中层采用高抗冲拉丝聚丙烯和成核剂混合，其添加量为高抗冲拉丝聚丙烯100kg和成核剂10kg；所述外层材料采用高抗冲拉丝聚丙烯100kg；挤出速度内：中：外速度是：26%: 37%：37%。
所述三元无规聚丙烯采用TF400树脂，茂金属低密度聚乙烯采用SP1520树脂。
所述高抗冲拉丝聚丙烯采用纯L5E89树脂。
内层添加开口剂，有效防止薄膜粘连，做成的成品包装袋保持良好的开口性，内层加茂金属SP1520，提升膜的热封强度及抗污染热封性能，解决产品在包装粉体及液体类内容物时热封不良的问题；中层添加成核剂，有效提升薄膜的挺度和刚度，增加成品的硬度，使成品袋拥有更好的直立效果，放置于柜台展示效果佳；增加内层的原料流量，有效降低膜的热封温度,提升膜的强度、拉力，有效降低膜的起封温度，制袋时采用较低的温度及热封时间，如制袋温度在165度、热封时间在350ms，就能达到产品要求，而传统的CPP膜制袋时采用的温度为180度、热封时间为400ms，这样就能极大提升制袋的产能和效率，降低废品率；生产出的成品透明性极好，满足客户对产品的高透明要求；薄膜在生产工艺上使用的树脂均是阻隔性能好的原材料，提高制袋膜的阻隔性和密闭性，从而提高膜的各项指标，防漏气，使食品的保香性更好，提高食品的保质时间。
申请实施例只是用于说明本申请所公开的技术特征，本领域技术人员通过简单的替换所进行的改变，仍然属于本申请所保护的范围。
