这种趋势适用于组合方便,更小的部分和创新的包装。这些消费者需求得到最近的IPSOS - 国际消费研究调查:消费者最欣赏的包装便利是:尺寸,易于处理和房屋存储,清晰的信息,高效保护,最终易于打开和重新关闭。在这些结果之后,奶酪生产商强调较小尺寸的容器,具有更宽的开口,以满足单一服务市场和易用性并重新使用。刚性托盘充满了好处,它们看起来很现代,在货架上脱颖而出,对零售商有积极的影响,总是吵嚷着货架准备的包装。如果用MAP包装的话,托盘里的奶酪有更长的保质期。带有气体喷射的受控真空系统无需将切片编织在一起,就能使氧气水平非常低。现在,许多品牌已经将薄而厚的切片奶酪放进了用气体冲洗的硬质托盘中。
托盘是醒目的包装和一个灵活的拉链包装的替代。它由刚性底部和密封在一起的柔性盖子组成。该托盘,一般聚丙烯,是由一个共挤片与氧阻隔层热成型。所述盖子的柔性薄膜材料为还包括氧气屏障的多层共挤材料。顶部是热成型的高冲击聚苯乙烯。用拉环可以很容易地把盖子从包装上扯下来。盖层通常为多层共挤膜(PP/PET或PP coex),其中包括防氧层,厚度可在200 - 500 μm之间。可剥托盘可以分为两个或多个部分,每个部分都有盖子,所以消费者可以去掉整个盖子,也可以只去掉一部分。用于奶酪片的气体冲洗托盘可以使修改后的空气保留在奶酪周围。这提高了产品的保质期,它对产品和风味的外观有积极的影响,并使它容易单独的切片分离。 In MAP, shelf life can be extended up to ten weeks. Sophisticated machineries flush out air from the packaging chamber and replace it with a correct defined mixture of gases, then seal the product in the packaging so that the product is maintained in a modified atmosphere environment. For soft cheese the appropriate atmosphere is a mixture of carbon dioxide and nitrogen; while for hard cheese an atmosphere of only carbon dioxide is more appropriate. During storage the carbon dioxide can dissolve into the water content of soft cheese and this reduces the volume of gas in the package, eventually causing the packaging to collapse. The presence of the nitrogen prevents this undesired effect. The flat surface of rigid trays provides unique product display options, direct printing or a adhesive label bearing store brand information can decor the lid while informative label with nutrition facts and other required information can take place on the tray bottom. Labels or marketing info always allow the consumer to see the whole product or at least part of it.
假设包装方便时,消费者更倾向于多花一点钱,奶酪包装商就会投资于更创新的可重新封闭的托盘,由三部分组成,一个蛤壳容器,其底部由一个盖子密封。有时盖子被拧成一个围绕托盘周长运行的通道。在家庭使用中,一旦柔性盖子被取下,消费者就可以接触到产品,然后将盖子扣回原位,以保护剩余的薄片。顶扣通常是热成型的。
打开并显示
刚性,奶酪的托盘也可以放入零售情况下垂直位置。这些案件认为,既可以缓解零售商的工作,并为店内浏览商店的浏览。含有通常为10到20件物品的环绕式案例通常是设计的,顶部和一侧可以在零售商的开口上没有任何努力,然后可以将开放式壳体放在商店货架上。站着的位置,在生产者提供的箱子或货架上,给机会向消费者展示产品的特点和独特的特点。另外一个特点是:托盘可以挂在木桩上,也可以平叠在井里。
奶酪切片和包装被带到全新的速度和自动化水平。最近的安装,很少有人需要从产品进入码垛和拉伸成品案件的产品中操作。线路设计有更多伺服电机,导致更快,更可重复的转换和更小的占地面积。自动热成型封装解决方案FFS从塑料薄膜卷轴开始,机器提供成品包装,为二级封装提供密封和/或真空和地图注射。对于较小的数量,该过程从预先形成的托盘开始。流程图可简化:形成模具站,填充,真空单元,气体注入站,封口站,切割站和端线。通过模块化模具,热成型站将扁平塑料薄膜转换为托盘,冷却后,UV站为顶部和底部薄膜提供有效的灭菌。奶酪日志由配备真空吸盘朝向切割机的机器人手臂处理。切片后,落下,托盘装载和托盘密封都在自动化线上完成。切割奶酪堆叠向前输送,而预成型托盘在输送机下方的位置拿着奶酪堆叠。 As the conveyor holding the cheese retracts, each of the stacks of cheese slices drops a very short distance into the trays Then the cycle repeats itself. The trays move next into the evacuation/backflush chamber, according to product requirements nitrogen or other protective gases can be filled into the package after vacuumizing the unwanted gases. The modified atmosphere cycle is PLC controlled. Once the lid is applied, the trays move next into a station where the preformed top are automatically applied to the trays. Top can be snapped onto the tray flange or snapped into a channel running around the perimeter of the tray. A gating mechanism creates lanes of sealed, lidded trays and leads them to check weighing, contaminants detection (metal detector or x-ray), labelling, and date-coding. Trays of cheese are placed into retail-ready cases, sweep arms take trayed cheese packages and push them into a case. From there the cases are pushed forward so that flaps can be folded and adhesive applied. The wraparound cases are conveyed to a palletizer/stretch wrapper. Each time it forms a layer of cases, that layer is lowered onto a stretch wrapper turntable and a stretch film is applied.
