Abstract

本实用新型涉及一种用于热加工肉类产品的、具有易开口能力的包装件。优选地，所述包装件意图用于以单份提供的热加工肉类产品。

Description

用于热加工肉类产品的、具有易开口能力的包装件
技术领域
本实用新型涉及一种用于热加工肉类产品的、具有易开口能力的包装件。优选地，所述包装件意图用于包装以单份提供的热加工肉类产品。
背景技术
在本实用新型的上下文中，术语香肠类型的“热加工肉类产品”指的是一种精细地或/和粗糙地粉碎的肉块，其已进行热处理，随后在真空下装入合适肠衣(casing)内。此外，术语“肉类产品”或“肉制品”指的包含热加工肉类产品或肉制品(基于精细地或粗糙地粉碎的肉块)的任意产品组。
常规用于热加工肉类产品的食品包装材料是天然的(从幼年反刍动物和猪的肠子获得)或者人工的(由纤维素、基于胶原的合成材料制成)。某些包装材料是可食用的(例如胶原蛋白肠衣)，而其它的包装材料需要在热处理之后剥离(例如，在法兰克福型香肠情况下的纤维素肠衣)。用于生产Parizer型的热加工肉类产品的合成肠衣例如可以是单层的或多层的，并构成保证产品的微生物学安全性的更安全方案。它们对氧呈现有限的渗透性(例如，在23℃和53％RH下，<15cm3/m2/d)，并且允许更长的保质期。然而，这种基于合成聚合物的肠衣不允许用手从最终产品中移除肠衣，不允许容易地接近产品。
此外，包装热加工肉类产品使用的常规肠衣并不意图用于包装单份，并且因产品类型和后处理阶段而不同。例如，比如parizers的肉制品以300gr项目提供，装入基于合成聚合物的肠衣中，或者它们在100-200gr产品的容器中以切片(平均切片重量为20克)提供。因此，在包装件打开的情况下，整个产品暴露于质量恶化因素。
实用新型内容
本实用新型的优点是，其提供了包装件的易开口能力，使得消费者能够在一天中的任何时刻容易地接近产品，而无需器具。此外，可呈现到热加工肉块的受控粘附，这有助于除去肠衣。本实用新型的另一优点是，本文所公开的包装件理想地用于单份肉类产品中。这样的潜能一方面保证了器官感觉/组织特征的保存，还保证了产品的微生物学安全性。这允许可消耗该产品的某些部分，而不用将更大的产品量暴露于质量恶化因素。
按照本实用新型，该包装件包括多层包装膜，其包括合成聚合物，提供了对氧(例如，<40cm3/m2/d)和水蒸汽(例如，<4g/m2/d)的有限渗透性、在第一阶段中以受控方式脱离单层的可能性以及到热加工肉块的受控粘附。
所述包装件包括热密封区域，其形成要填塞的容器的形状，并位于所述容器的纵轴上。该包装件还包括非密封表面，其平行于热密封区域延伸。该非密封表面具有垂直于热密封区域的至少一个撕裂凹口，其允许通过旋转运动打开包装件。根据本实用新型的优选实施例，本文所公开的包装件意图用于包装重量从5至70gr的单份肉类产品，以减少将较大量的所述产品暴露于可能恶化其质量的因素(例如，微生物学风险)。
附图说明
图1示出优选的实施例。
具体实施方式
图1示出具有易开口能力的包装件10。所述包装件通过热密封过程形成为筒状。热密封过程限定出位于容器11纵轴上的热密封区域。自由的非密封表面12平行于热密封区域延伸，其特征在于存在垂直于热密封区域的撕裂凹口13，撕裂凹口允许通过旋转运动除去包装件。
本实用新型的包装件由包括单独材料层(叠层)的包装材料制成，其允许：I)对氧(例如，<40cm3/m2/d)和水蒸汽(例如，<4g/m2/d)的受控渗透性，并因此保护封装的热加工肉块，II)包装件的易开口能力(易剥离)，即容易在初始阶段以受控的方式脱离单层，以便开始除去包装件的过程，III)到热加工肉块的受控粘附，以便有助于除去包装件。
通过使用多层包装膜满足了上述要求I)至III)，多层包装膜基本上由聚合物组成，诸如聚乙烯(PE)和聚酰胺(PA)。
多层包装膜通过热密封工艺(例如，温度范围在162-168℃之间)采用肠衣的形式。具体地，具有期望结构和宽度的多层包装膜(厚度例如为80μm)形成为筒状，并且在热密封过程下其采取肠衣作为最终形式。热密封过程限定出位于容器纵轴上的热密封区域。
根据本实用新型的优选实施例，多层包装膜的直接接触肉块的层包括聚乙烯(PE)。更优选地，多层包装膜的外层也包括聚乙烯(PE)。甚至更优选地，多层包装膜的中间层基于聚酰胺(PA)。
为了便于用手容易地打开包装件，包装件具有自由的非密封表面12，其是包装件的组成部分。自由的非密封表面在热密封过程中形成，并与热密封区域11平行，因此还平行于容器的纵轴。此外，包装件的自由的非密封表面具有至少一个撕裂凹口，其垂直于热密封区域13的纵轴，并便于通过旋转运动容易地打开包装件。优选地，该非密封表面具有多个撕裂凹口，这与它的长度可比拟。优选地，在热密封过程之后，多层包装膜在意图形成非密封表面的一部分的一侧具有撕裂凹口。如此，要用肉块填塞的准备好的肠衣的非密封表面具有垂直于热密封区域的纵轴的许多撕裂凹口。撕裂凹口限定出相对的平行四边形，其尺寸应允许用手简单地打开包装件。
此外，本实用新型涉及本文所公开的包装件的用途，用于包装重量从5至70gr的单份热加工肉类产品，这允许消费者可消耗热加工肉类产品的某些部分，而不用将它的更大量暴露于质量恶化因素。
