Linear Wraparound Case Packer

In end-of-line packaging for beverage, food, and personal care manufacturing plants, wraparound case packing has emerged as an advanced technology replacing traditional carton packaging methods. The Linear Wraparound Case Packer is a fully enclosed, linear-motion automated system that performs product grouping, flat carton blank feeding, tight blank folding around products, and high-speed, high-precision hot-melt glue sealing.

What is a Linear Wraparound Case Packer?

A Linear Wraparound Case Packer is an automatic case packing machine operating on a straight-line (linear) transfer principle. Instead of using pre-glued regular slotted containers (RSC) with higher unit costs, the machine utilizes flat corrugated blanks.

The system automatically folds and wraps the flat corrugated blank tightly around a pre-grouped matrix of products (bottles, cans, jars, or cartons), then applies hot-melt adhesive to form a fully secured, finished case.

Automated Operational Process:

• Product Infeed & Laning: A linear conveyor feeds bottles, cans, or containers into the machine and divides them into parallel lanes.
• Grouping & Collation: A matrix collation mechanism arranges products into grouped bundles (e.g., 2×3, 3×4, 4×6).
• Flat Blank Feeding: A vacuum suction arm picks individual flat corrugated blanks from the magazine and positions them underneath the grouped products.
• Wraparound Case Folding: A linear-driven folding arm system folds the blank edges tightly around all four sides of the product bundle.
• Hot-Melt Glue Application & Sealing: Automatic glue nozzles apply hot-melt adhesive onto joining flaps, pressing them tightly to complete a rigid case seal.
• Finished Case Discharge: Square, tightly wrapped cases are transferred to downstream barcode printing, labeling, or robotic palletizing stations.

Machine Applications

The Linear Wraparound Case Packer offers high customizability and compatibility across various packaging formats and industries:

Diverse Product Packaging Formats:

• PET bottles, glass bottles (mineral water, beverages, cooking oil, liquid detergent).
• Aluminum cans, tin cans (beer, soft drinks, canned foods).
• Paper cartons, small boxes, plastic/glass jars, pharmaceutical bottles.

Diverse Case Formats:

• Fully enclosed wraparound cases
• Open-top corrugated trays
• Corrugated trays with shrink-wrap

Applicable Industries:

• Beverage & Brewing: Beverage plants, breweries, mineral water, fruit juices, bottled milk.
• Food & Edible Oils: Bottled cooking oil, fish sauce, soy sauce, canned foods, seasonings.
• Personal Care & Household Chemicals: Shampoo, body wash, laundry detergent, fabric softeners, floor cleaners.
• Pharmaceuticals & Industrial Products: Medicine bottles, IV fluid bottles, bottled chemicals.

Technical Specifications

Key Advantages

• 15% – 20% Board Material Savings: Utilizing flat blanks significantly reduces material procurement costs compared to traditional pre-glued RSC cases.
• Tightly Wrapped Formats: Corrugated blanks fold tightly around product matrixes, eliminating interior void space to create rigid, highly stackable cases for warehousing.
• Full Servo Linear Drives: Blank feeding, product transfer, flap folding, and glue application are driven by servo motors for smooth, precise, low-noise operation.
• Precision Hot-Melt Adhesive System: Metered glue nozzles deliver instant bonding with thin, clean glue lines that prevent carton smudging.
• Quick Product Changeovers: Modular engineering supports flexible size adjustments for different bottle/can types or packing patterns (2×3, 3×4, etc.).
• International-Standard Safety Enclosures: Fitted with heavy-duty tempered glass/polycarbonate safety guards and safety interlock sensors that halt operation automatically when doors are opened.

Business Benefits

• Optimized Freight & Warehousing Overhead: Precise, square wraparound cases maximize pallet utilization and container loading density, lowering logistics costs.
• Superior Product Protection: Internal contents are firmly secured against shifting, vibration, and impact, preventing dented cans or broken glass bottles during distribution.
• Higher Automation Levels: Completely replaces manual case erecting, top loading, and tape sealing, cutting 4–6 operators per line.
• Professional Packaging Aesthetics: Concealed internal glue seams keep external carton faces clean and flat, boosting shelf presentation and brand value.
