The common packaging forms of paper cup packaging machines are primarily designed based on the usage scenarios of paper cups, packaging efficiency, storage and transportation needs, and whether dustproof or moistureproof functions are required. Below are ten common packaging forms along with their characteristics:
1. Single Independent Packaging (Single-Cup Packaging)
Form: A single paper cup is fully wrapped in film (e.g., PE film), with the edges heat-sealed to form an individual package. Some packages feature printed brand information or usage instructions.
Features: Excellent sealing performance effectively prevents dust and moisture, avoiding contamination of individual cups. It is ideal for scenarios involving direct contact with food (e.g., milk tea cups, coffee cups).
Applicable Scenarios: Commercial disposable paper cups (sold individually or for immediate use) and high-end beverage packaging.
2. Multi-Cup Stacked Film Packaging (Trayless Stacking)
Form: Multiple paper cups (typically 5–20) are stacked with their openings facing downward, then entirely wrapped in heat-shrinkable film. After heat shrinking, the film adheres tightly to the cups, forming a fixed shape.
Features: Compact packaging saves space and offers strong stacking stability, making it suitable for bulk storage and transportation.
Note: Stack height must be controlled (excessively tall stacks may tip over), and the cups themselves must have sufficient stiffness to avoid deformation during stacking.
Applicable Scenarios: Household disposable paper cups (standard packaging sold in supermarkets) and bulk packaging for office use.
3. Multi-Cup Arranged Packaging (With Partitions/Trays)
Form: Paper cups are arranged at fixed intervals (e.g., 2×3, 3×4) and supported by a paper or plastic tray at the bottom. They are then wrapped in film or packed into boxes, with some designs including spacing between cups.
Features: Prevents cup deformation from stacking and 挤压,making it particularly suitable for cups with soft, easily collapsible rims (e.g., ultra-thin paper cups).
Applicable Scenarios: Precisely packaged disposable paper cups and cups for export or long-distance transportation (to reduce collision damage).
4. Paper Box/Carton Packaging
Form: Stacked paper cups (or film-wrapped cup sets) are placed into paper boxes or cartons. Cushioning paper may be added inside to prevent shaking, while specifications, quantity, and other details are printed on the exterior.
Features: Strong protective performance and resistance to 挤压 make it suitable for large-scale warehousing and long-distance transportation. Additionally, paper boxes are recyclable (offering good environmental benefits).
Applicable Scenarios: Industrial-grade bulk supply (e.g., large-pack paper cups for catering businesses) and full-box paper cups sold by e-commerce platforms.
5. Heat-Shrink Film Collective Packaging (Group Fixation)
Form: Multiple film-wrapped stacked cup sets (e.g., 2–4 sets) are entirely wrapped in large-size heat-shrinkable film. After heat shrinking, they form a larger collective package (e.g., 100–200 cups per group).
Features: Exceptional fixation reduces scattering during transportation, making it suitable for large-volume wholesale.
Applicable Scenarios: Intermediate transportation from warehouses to retailers and bulk packaging in large supermarkets (pre-packaging before bulk weighing).
6. Anti-Pressure Cushioned Packaging (With Support Structures)
Form: A paper or plastic protective ring is placed around the exterior of each cup (focusing on reinforcing the rim and base), followed by stacking or arranging the cups for packaging. Some designs include cushioning cotton inside the package.
Features: Specifically addresses the "ease of crushing" issue with paper cups, protecting rim flatness and cup body stiffness.
Applicable Scenarios: High-end customized paper cups (e.g., advertising cups with printed patterns) and fragile cups with thin walls.
7. Transparent Window Packaging (Display Packaging)
Form: Paper boxes or composite film packaging are used, with a transparent window (e.g., a PET film window) cut into the surface to allow direct visibility of the cup's style, color, or printed pattern.
Features: Combines protection with display functionality, enabling consumers to visually assess cup appearance and boosting purchase intent.
Applicable Scenarios: Decorative paper cups sold at retail (e.g., holiday-themed cups, cartoon-patterned cups).
8. Moisture-Proof Sealed Packaging (Aluminum-Plastic Composite Film)
Form: Paper cups are sealed in aluminum-plastic composite film (which offers strong water and oxygen resistance). They may also be vacuum-sealed or filled with inert gas to extend shelf life.
Features: Excellent moisture resistance and contamination prevention, making it suitable for storage in high-humidity environments (e.g., southern rainy seasons) or long-term storage (e.g., backup inventory).
Applicable Scenarios: Paper cups requiring long-term storage and cups transported or sold in high-humidity regions.
