Description
本發明係有關於保存容器相關之技術領域，尤其是指一種製備具保鮮塗料之保鮮紙箱之方法。 The invention relates to the technical field related to storage containers, in particular to a method for preparing a fresh-keeping carton with a fresh-keeping coating.
隨著氣候及環境改變日趨劇烈，在運輸過程中食材鮮度保持變得越來越重要，而環保意識提升，包裝材料的回收或是再利用也逐漸被重視，以瓦楞紙箱為主的包裝材料，具有容易進行運輸、儲存、保護內容物以及利於回收作業的特性，故廣為業界所使用。 With climate and environmental changes becoming more and more severe, it is becoming more and more important to maintain the freshness of food materials during transportation. With the improvement of environmental protection awareness, the recycling or reuse of packaging materials is also gradually paid attention to. The main packaging materials are corrugated boxes. It is easy to transport, store, protect the contents, and facilitate recycling operations, so it is widely used in the industry.
蔬菜在運輸過程容易損耗的主要原因，是蔬菜在採收後仍然具有生命，也會進行呼吸活動，蔬菜保鮮就是利用包裝材料達成氣調包裝MA(Modified Atmosphere)，使蔬菜在具輕微透氣性包裝材料密封下，經由蔬菜本身的呼吸作用增加或減少包材內某類氣體，並且控制氣體成分比率，藉此延長冷藏生鮮食品貯存壽命方法之一。 The main reason why vegetables are easy to lose during transportation is that vegetables still have life after harvesting, and they will also undergo breathing activities. Vegetable preservation is to use packaging materials to achieve modified atmosphere packaging (MA (Modified Atmosphere), so that vegetables are packaged in a slightly breathable package. It is one of the methods to prolong the storage life of refrigerated fresh food by increasing or reducing a certain type of gas in the packaging material through the respiration of the vegetable itself under the sealing of the material, and controlling the gas composition ratio.
但坊間之瓦楞紙箱由於透氣好，表面粗糙易於細菌長生且抗菌效果差，對於食材鮮度保持有不易持久的缺點。因此，如何能藉由相關工藝改善瓦楞紙箱調節氣體與抑菌效果，讓瓦楞紙箱內能形成氣調包裝MA之環境，其紙箱之製法實有其改善之必要。 However, the corrugated boxes in the market have good air permeability, rough surface, easy to grow bacteria and poor antibacterial effect, which is not easy to maintain the freshness of food materials for a long time. Therefore, how to improve the gas-regulating and antibacterial effects of corrugated cartons through related processes, so that an environment for modified atmosphere packaging MA can be formed in corrugated cartons, and the manufacturing method of the cartons must be improved.
本發明的目的是在提供一種製備具保鮮塗料之保鮮紙箱之方法，用以達成氣調包裝環境之需求，克服先前技藝之缺失。 The purpose of the present invention is to provide a method for preparing fresh-keeping cartons with fresh-keeping coatings to meet the requirements of the modified atmosphere packaging environment and overcome the lack of prior art.
根據本發明上述目的，本發明提出一種製備具保鮮塗料之保鮮紙箱之方法，包括製備主體溶液、混合抗菌劑、塗佈保鮮塗料、及製成保鮮紙箱等步驟。取丙烯酸樹脂混合一矽氧烷衍生物，再混合一海藻酸鈉溶液或(及)普魯蘭多醣溶液形成主體溶液，再混合抗菌劑形成保鮮塗料，配合塗佈工藝將保鮮塗料塗佈於一紙材上，最後將紙材複層貼合成紙板，並製成保鮮紙箱。藉由上述方法製備之保鮮紙箱作為蔬果包裝時，可以提供氣調包裝所需之環境，延長蔬果新鮮時程。 According to the above purpose of the present invention, the present invention proposes a method for preparing a fresh-keeping carton with a fresh-keeping coating, including the steps of preparing a main body solution, mixing an antibacterial agent, coating a fresh-keeping coating, and making a fresh-keeping carton. Take acrylic resin mixed with a siloxane derivative, then mixed with a sodium alginate solution or (and) pullulan solution to form a main solution, and then mixed with an antibacterial agent to form a fresh-keeping coating, and apply the fresh-keeping coating on a Finally, the paper is laminated into cardboard and made into a fresh-keeping carton. When the fresh-keeping carton prepared by the above method is used as fruit and vegetable packaging, it can provide the environment required for the modified atmosphere packaging and prolong the freshness of the fruits and vegetables.
