食品包装食品安全导刊年第6期□本刊记者房慧实习记者卜庆婧个性化,Stick 包装广受追捧——访仅一包装设备有限公司市场部经理许彩萍容易起皱的问题,可给消费者带来更高档、美观、精致的感官体验。
4.有效延长保质期,对于奶粉等产品,需要充入氮气来保证产品的品质,而以往400g 软包装一旦开启,其中的氮气就会完全散失,且每次重复开启包装都会对剩余产品的质量造成影响(如袋口的二次污染等),而Stick 包装则不会出现类似问题,同等质量的奶粉由多条独立的Stick 包装组成,消费者可根据实固体饮料市场在经历了玻璃瓶、400g 或200g 软袋包装、三边封或四边封方形袋等包装形式后,又出现了一种新概念——长条状包装(Stick )。
如今,Stick 包装已成为最流行的包装形式之一,在乳制品、固体饮料、药品等行业中的使用量不断增加,尤其为固体饮料中的高端产品所普遍采用,如雀巢咖啡、麦斯威尔咖啡、卡夫果珍等产品都已开始使用了该包装。
在包装行业历经二十年风雨的仅一包装设备有限公司顺应市场需求,于2006年与日本东阳合作,成功推出了高性能的Stick 包装机,本刊邀请到仅一公司市场部经理许彩萍请她讲述研制生产Stick 包装的心得。
优点诸多,St ick 包装成固体食品包装领域新秀与传统软袋包装相比,Stick 包装的诸多优点促进了其在市场的推广及使用量上的增长。
1.容易携带,Stick 包装因其造型小巧,可装进钱包、口袋或运动包中,便于携带,易于储存,其独特的双易撕口开口方式更是随时都可进行开包,方便食用,也给了产品独有的不可复制的防伪标识。
2.使用更方便,倾倒更彻底,不易造成粉末散落,与从前的方形袋相比,Stick 包装易于倾倒,绝不会将细粉类物料如咖啡或果汁粉等的粉末散落到杯子外面。
3.不易变形,Stick 包装产品通常放置在纸盒外包装内,所以避免了在展示、出售过程中软袋包装形状不规则、722008际需要逐条开启,不会因一条Stick包装的开启而影响其他的质量,从而延长了此类产品的保质期。

电子元器件包装载带以及要求
承载带简称载带英文名称载带指的广泛应用于IC、电阻、电感、电容、连接器、LED、保险丝、开关、继电器、接插件、振荡器、二、三极管、手机屏蔽框等SMT电子元件的包装塑胶载体。
SMT元件的发展及与载带的关系,在上个世纪SMT表面安装技术的出现使电子产品产生巨大的变革。
目前绝大多数PCB或多或少采用了这项低成本、高效率、缩小PCB板体积的生产技术。
SMT被广泛采用促进了SMD表面安装器件的发展.原先的插孔式元器件被SMD元器取代成为必然,同时人们对手机、电脑等电子产品的小体积、多功能的要求.更促进了SMD元器向高集成、小型化发展。
除其它运输载体如托盘,塑管等外元器件还必须要有能够在SMT机上被高速自动化运用所需的运输载体——SMD载带系统。
从保护、经济、容量等方面考虑.载带系统也颇有优势:这就是为什么在SMT生产线上看到的SMD元器件的载体绝大数是载带系统纸基材与塑料基材,对载带系统的要求
1. 首先,对载带提出了高精度的要求三大元源元器件电阻、电容、电感从
长引脚变成SMD后体积不断缩小,现已出现0402封装,在不久的将来,0201封装将会被大量采用。
在SMT设备方面也已经出现0201的使用设备。
这些元器件的小型化带动了载带系统的变化。
2. 其次,SMT机器取放元器件及分立元器件的速度越来越快,1个周期已小
于0.09秒,对载体的强度提出高耐拉强度的要求
3. 其三,对成本降低,提高密度包装提出要求,包装间距2mm通常为
4. 最后,防静电保护,由于元器件非常小,很容易被静电吸附,导致SMT机取

斜角丝带包装礼盒方法
斜角丝带包装礼盒是一种常见的包装方法,可以让礼盒看起来更加精致和美观。
下面是一种简单的斜角丝带包装礼盒的方法:
材料:
- 礼盒
- 礼盒包装纸
- 斜角丝带
- 剪刀
- 胶带
步骤:
1. 首先,将礼盒放在包装纸上,并确定纸的大小,使其能够完全包住礼盒。
2. 将礼盒放置在包装纸的中央,然后将纸的一侧折叠到盒子的上方,并使用胶带固定住。
3. 接下来,将纸的另一侧折叠到盒子的下方,与之前的一侧呈现出斜角形状,并使用胶带固定住。
4. 将包装纸的两侧折叠到盒子的两侧,形成完整的包装纸,然后使用胶带固定住。
5. 取一段斜角丝带,并将其叠放在盒子的一个角上。
6. 将丝带固定在盒子上,可以使用胶带或打个可爱的蝴蝶结来固定住。
7. 将斜角丝带的另一端叠放在盒子的对角线上,形成交叉样式。
8. 将丝带再次固定在盒子上,确保丝带交叉处不松动。
9. 根据需要,可以在丝带的交叉处打结、创意地扎成蝴蝶结,或者将丝带修剪成合适的长度。
10. 完成礼盒的斜角丝带包装。
这是一种简单的斜角丝带包装礼盒的方法,可以根据实际需要进行调整和创新,增加不同的装饰元素,打造出独特而美丽的包装效果。
恒量自动化包装产线的指标恒量自动化包装生产线是一种高精度、高效率的包装系统,它能够确保产品在包装过程中的重量、体积、数量等关键指标保持恒定。
这种生产线通常用于食品、化工、医药等行业,以确保产品的一致性和消费者的满意度。
以下是恒量自动化包装生产线的一些关键指标:1. 精度:恒量自动化包装生产线的主要指标之一是包装精度,即系统能够在设定的范围内保持恒定的包装量。
这通常以百分比或绝对值来表示,例如±1%或±2克。
高精度的包装线能够减少产品浪费,提高生产效率。
2. 速度:包装速度是指生产线每单位时间内完成的产品包装数量。
恒量自动化包装生产线需要在保证精度的同时,达到较高的包装速度,以满足生产需求。
速度通常以每分钟包装的产品数来衡量。
3. 可靠性:恒量自动化包装生产线的可靠性是指其在连续运行过程中的稳定性和故障率。
高可靠性的生产线能够减少停机时间,提高整体设备效率。
4. 灵活性:灵活性是指包装生产线能够适应不同产品规格和包装要求的能力。
这包括能够快速更换模具、调整机器参数以适应不同的包装尺寸和类型。
5. 安全性:安全性是指包装生产线在操作过程中对操作人员的保护程度。
这包括机器的安全防护装置、紧急停止按钮、安全操作规程等。
6. 易于维护:易于维护的包装生产线可以减少维修时间和成本。
这包括易于访问的部件、清晰的维护指南、预防性维护计划等。
7. 自动化程度:自动化程度是指包装生产线在包装过程中自动完成任务的比率。
高度自动化的生产线可以减少人工干预,提高生产效率和一致性。
8. 节能环保:节能环保是指包装生产线在运行过程中对能源的消耗和对环境的影响。
节能的生产线可以降低运营成本,减少对环境的影响。
9. 防止交叉污染:特别是在食品和医药行业,防止交叉污染是非常重要的。
恒量自动化包装生产线需要采取措施,如使用隔离系统、清洁设计、适当的材料选择等,以确保产品安全。
10. 数据追踪和集成:现代的恒量自动化包装生产线通常配备有数据追踪和集成系统,如物联网、工业4.0技术等,这些系统可以实时监控生产数据,提供生产效率分析,帮助优化生产过程。
数据线纸卡包装设计方案
1. 简洁明了的设计:数据线是一种功能性产品,因此包装设计应该简洁、明了,突出产品的特点和使用场景。
使用清晰的字体和图标,以及简洁的色彩搭配,让消费者一眼就能理解产品的功能和优势。
2. 品牌标识和主题色彩:在包装上突出品牌标识和主题色彩,以增强品牌的辨识度。
可以选择符合品牌形象的配色方案,并将品牌标识置于易于注意的位置,例如包装正面或顶部。
3. 产品特点的展示:通过设计元素和图形,突出数据线的特点,例如快速充电、高速传输等。
可以在包装上使用图表、示意图或文字说明,以便消费者快速了解产品的功能和用途。
4. 可持续包装:考虑使用环保材料制作包装,以符合现代消费者对可持续性的关注。
选择可回收、可降解的纸板或纸质材料,并避免使用过度包装,减少对环境的负面影响。
5. 便利性和保护性:为了提供方便的使用体验,可以在包装设计中考虑一些便利性的元素,例如易于打开的拉绳或翻盖设计。
此外,包装也应提供足够的保护,以确保产品在运输和存储中不受损。

四边封袋、三边封袋和背封袋的优缺点对比四边封袋即成袋后四条边均经过热封的包装形式,目前最常见的颗粒剂包装形式,技术成熟,工艺简单。
设备运行稳定性高,造型相对美观,产品密封性较好。
四边封袋通常使用一整张膜等分为两半后相对包装,属于先整体热封制袋后进行单袋裁剪的方式,生产时只需要控制一条边对齐即可获得较好的包装效果,因此具有极高的包材/设备适应性和包装运行稳定性(这一点非常重要,由于四边封袋机速度通常慢于装盒机,常见的模式为多台四边封袋机配合一台装盒机使用,对于设备运行稳定性的要求较高)。
同时,由于每条边都经过均匀的热封,成袋后的产品密封性较好。
四边封袋的缺点是对大体积物料的包装适应性不足,由于是整张膜先制袋后裁剪,因此要求制袋时复合膜相对平整,制袋后袋体为平面,难以装入大体积物料,袋内空间利用率相对较低。
三边封袋即包装袋一侧为复合膜直接对折,另外三条边为热封边的形式。
实际上三边封袋可以视为四边封袋的补充。
相对于四边封袋来说,其优点是成袋后可以先展开成立体袋型,空间利用率高,适合大体积包装需求,常用于感冒冲剂等产品的包装。
三边封袋的缺点同样明显,首先是三条边热封造成的袋型不对称影响美观,当然美观问题仁者见仁,这里不多讨论。
其次是包装速度较慢,三边封袋机最常见的包装形式为单列包装(这也是三边封适合大体积包装的原因,由于只是单列可以不考虑复合膜平整性的要求),多列式的三边封袋机我没有见过,但可以想象如果有的话,多列式三边封袋只能采用先将复合膜裁剪为数条再分别卷制成袋的方式,其控制难度之高还不如多台单列包装机组合使用来的稳定。
背封袋(也称Stick包装)即卷膜先分切为数列,每列复合膜单独卷制纵封后将纵封边压向一侧,然后横封制袋的方式,最初由**企业发明。
背封袋的优点非常明显,首先是外形非常美观,背封袋采用的隐藏式纵封边和袋型特点决定了其外观特点鲜明,袋型精致美观,与同类型的四边封产品相比有明显的差异化优势。
