首先就是確定材質(zhì)，材質(zhì)的選擇有塑料類的、紙質(zhì)類的、生物可降解的材料，當(dāng)然不同的材料價格也不同，這個的選擇主要還是看您要裝什么物。

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.

塑料類打包盒制作?

Production of plastic packaging boxes

注塑成型：將 PP、PS 等塑料顆粒投入注塑機(jī)料筒，通過加熱使其熔融。在螺桿的推動下，熔融的塑料注入模具型腔中，經(jīng)過冷卻定型后，開模取出成型的打包盒。模具的設(shè)計(jì)決定了打包盒的形狀、尺寸和結(jié)構(gòu)，高精度的模具能確保產(chǎn)品的一致性和質(zhì)量。注塑過程中，需嚴(yán)格控制溫度、壓力和注塑時間等參數(shù)，以保證產(chǎn)品的外觀和性能。?

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：先將塑料片材加熱至軟化狀態(tài)，然后通過真空或壓力吸附在模具表面，冷卻后定型。吸塑成型適用于制作薄壁、形狀簡單的打包盒，如一次性塑料餐盒的蓋子。生產(chǎn)時，需根據(jù)不同的塑料材質(zhì)調(diào)整加熱溫度和時間，確保片材均勻軟化，避免出現(xiàn)變形、厚薄不均等問題。

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.

紙質(zhì)類打包盒制作?

Production of paper packaging boxes

印刷：根據(jù)設(shè)計(jì)要求，在白卡紙或牛皮紙上進(jìn)行圖案、文字印刷。采用食品級油墨，確保印刷內(nèi)容無毒無害。印刷工藝包括膠印、柔印、凹印等，不同的印刷方式適用于不同的圖案和紙張類型。印刷過程中，要保證圖案清晰、色彩準(zhǔn)確，套印誤差控制在極小范圍內(nèi)。?

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：將印刷好的紙張通過模切機(jī)，利用刀具按照預(yù)定的形狀和尺寸進(jìn)行切割和壓痕。模切刀的精度和質(zhì)量直接影響打包盒的成型效果，切割后的紙張需邊緣整齊、無毛邊，壓痕清晰，便于后續(xù)折疊成型。?

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. ?

折疊組裝：人工或通過自動化設(shè)備，將模切好的紙張按照壓痕進(jìn)行折疊，使用膠水、訂書釘或超聲波焊接等方式進(jìn)行組裝，形成完整的打包盒。組裝過程中，要確保各部件連接牢固，無松動、脫膠現(xiàn)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藝與塑料類和紙質(zhì)類有相似之處，但也有特殊要求。以 PLA 為例，在注塑或吸塑成型過程中，由于 PLA 的加工溫度范圍較窄，對溫度控制的要求更為嚴(yán)格，過高或過低的溫度都會影響產(chǎn)品質(zhì)量。同時，為了提高其機(jī)械性能和耐水性，可能會在生產(chǎn)過程中添加特殊的助劑或進(jìn)行表面處理。?

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. ?

質(zhì)量檢測與包裝

Quality Inspection and Packaging

外觀檢測：檢查打包盒表面是否平整、光滑，有無氣泡、劃痕、變形等缺陷，印刷圖案是否清晰、完整，顏色是否符合要求。?

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. ?

尺寸檢測：使用卡尺、卷尺等工具測量打包盒的尺寸，確保其符合設(shè)計(jì)規(guī)格，誤差在允許范圍內(nèi)。?

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. ?

物理性能檢測：對塑料類打包盒進(jìn)行耐熱性、耐寒性測試，檢測其在高溫或低溫環(huán)境下是否會變形、開裂；對紙質(zhì)類和生物可降解材料打包盒進(jìn)行耐水性、耐油性測試，評估其在接觸水分或油脂時的性能表現(xiàn) 。此外，還會進(jìn)行抗壓強(qiáng)度測試，檢查打包盒在承受一定重量時是否會損壞。?

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. ?

衛(wèi)生安全檢測：依據(jù)食品接觸材料的相關(guān)標(biāo)準(zhǔn)，對打包盒進(jìn)行微生物檢測、重金屬含量檢測等，確保其不會對人體健康造成危害。

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.
