首先就是确定材质，材质的选择有塑料类的、纸质类的、生物可降解的材料，当然不同的材料价格也不同，这个的选择主要还是看您要装什么物。

The first step is to determine the material, which can be plastic, paper, or biodegradable. Of course, different materials have different prices, and the choice mainly depends on what you want to pack.

塑料类打包盒制作?

Production of plastic packaging boxes

注塑成型：将 PP、PS 等塑料颗粒投入注塑机料筒，通过加热使其熔融。在螺杆的推动下，熔融的塑料注入模具型腔中，经过冷却定型后，开模取出成型的打包盒。模具的设计决定了打包盒的形状、尺寸和结构，高精度的模具能确保产物的一致性和质量。注塑过程中，需严格控制温度、压力和注塑时间等参数，以保证产物的外观和性能。?

Injection molding: Put plastic particles such as PP and PS into the material cylinder of the injection molding machine and melt them by heating. Under the push of the screw, molten plastic is injected into the mold cavity. After cooling and shaping, the mold is opened to take out the formed packaging box. The design of the mold determines the shape, size, and structure of the packaging box, and high-precision molds can ensure product consistency and quality. During the injection molding process, it is necessary to strictly control parameters such as temperature, pressure, and injection time to ensure the appearance and performance of the product. ?

吸塑成型：先将塑料片材加热至软化状态，然后通过真空或压力吸附在模具表面，冷却后定型。吸塑成型适用于制作薄壁、形状简单的打包盒，如一次性塑料餐盒的盖子。生产时，需根据不同的塑料材质调整加热温度和时间，确保片材均匀软化，避免出现变形、厚薄不均等问题。

Blister molding: First, heat the plastic sheet to a softened state, then attach it to the surface of the mold through vacuum or pressure, and cool it before shaping. Vacuum forming is suitable for making thin-walled, simple shaped packaging boxes, such as the lid of disposable plastic lunch boxes. During production, it is necessary to adjust the heating temperature and time according to different plastic materials to ensure uniform softening of the sheets and avoid deformation and uneven thickness.

纸质类打包盒制作?

Production of paper packaging boxes

印刷：根据设计要求，在白卡纸或牛皮纸上进行图案、文字印刷。采用食品级油墨，确保印刷内容无毒无害。印刷工艺包括胶印、柔印、凹印等，不同的印刷方式适用于不同的图案和纸张类型。印刷过程中，要保证图案清晰、色彩准确，套印误差控制在极小范围内。?

Printing: According to design requirements, print patterns and text on white cardboard or kraft paper. Using food grade ink to ensure non-toxic and harmless printing content. Printing techniques include offset printing, flexographic printing, gravure printing, etc. Different printing methods are suitable for different patterns and paper types. During the printing process, it is important to ensure clear patterns, accurate colors, and minimal overlay errors. ?

模切：将印刷好的纸张通过模切机，利用刀具按照预定的形状和尺寸进行切割和压痕。模切刀的精度和质量直接影响打包盒的成型效果，切割后的纸张需边缘整齐、无毛边，压痕清晰，便于后续折迭成型。?

Die cutting: The printed paper is cut and creased using a die cutting machine and cutting tools according to the predetermined shape and size. The accuracy and quality of the die-cutting knife directly affect the forming effect of the packaging box. The cut paper should have neat edges, no burrs, clear indentation, and be easy to fold and form later. ?

折迭组装：人工或通过自动化设备，将模切好的纸张按照压痕进行折迭，使用胶水、订书钉或超声波焊接等方式进行组装，形成完整的打包盒。组装过程中，要确保各部件连接牢固，无松动、脱胶现象。

Folding assembly: Manually or through automated equipment, the die cut paper is folded according to the indentation, and assembled using glue, staples, or ultrasonic welding to form a complete packaging box. During the assembly process, it is important to ensure that all components are securely connected without any looseness or detachment.

生物可降解材料打包盒制作?

Production of biodegradable material packaging boxes

生物可降解材料打包盒的制作工艺与塑料类和纸质类有相似之处，但也有特殊要求。以 PLA 为例，在注塑或吸塑成型过程中，由于 PLA 的加工温度范围较窄，对温度控制的要求更为严格，过高或过低的温度都会影响产物质量。同时，为了提高其机械性能和耐水性，可能会在生产过程中添加特殊的助剂或进行表面处理。?

The production process of biodegradable material packaging boxes is similar to that of plastic and paper products, but there are also special requirements. Taking PLA as an example, in the process of injection molding or vacuum forming, due to the narrow processing temperature range of PLA, the requirements for temperature control are more stringent. Excessive or insufficient temperature can affect product quality. Meanwhile, in order to improve its mechanical properties and water resistance, special additives or surface treatments may be added during the production process. ?

质量检测与包装

Quality Inspection and Packaging

外观检测：检查打包盒表面是否平整、光滑，有无气泡、划痕、变形等缺陷，印刷图案是否清晰、完整，颜色是否符合要求。?

Appearance inspection: Check whether the surface of the packaging box is flat and smooth, whether there are defects such as bubbles, scratches, deformation, etc., whether the printed pattern is clear and complete, and whether the color meets the requirements. ?

尺寸检测：使用卡尺、卷尺等工具测量打包盒的尺寸，确保其符合设计规格，误差在允许范围内。?

Size inspection: Use tools such as calipers and tape measures to measure the size of the packaging box, ensuring that it meets the design specifications and the error is within the allowable range. ?

物理性能检测：对塑料类打包盒进行耐热性、耐寒性测试，检测其在高温或低温环境下是否会变形、开裂；对纸质类和生物可降解材料打包盒进行耐水性、耐油性测试，评估其在接触水分或油脂时的性能表现 。此外，还会进行抗压强度测试，检查打包盒在承受一定重量时是否会损坏。?

Physical performance testing: Conduct heat and cold resistance tests on plastic packaging boxes to determine if they will deform or crack in high or low temperature environments; Conduct water and oil resistance tests on paper and biodegradable packaging boxes to evaluate their performance when exposed to moisture or oil. In addition, a compressive strength test will be conducted to check whether the packaging box will be damaged when subjected to a certain weight. ?

卫生安全检测：依据食品接触材料的相关标准，对打包盒进行微生物检测、重金属含量检测等，确保其不会对人体健康造成危害。

Health and safety testing: According to the relevant standards for food contact materials, microbiological testing and heavy metal content testing are carried out on packaging boxes to ensure that they do not pose a threat to human health.
