One-Piece Wrap-Around Case Packer

Engineered with precision motion control and powered by globally recognized electrical components, this machine delivers consistent pack quality at speeds up to 25–30 cases per minute, depending on product and case size. It is particularly suited for glass bottles, PET bottles, stand-up pouches, and carton-based products commonly found in juice, water, sauce, and fermented bean curd production lines.

As a manufacturer with over 1,300 client installations across China and Southeast Asia, Wanying has refined this equipment through years of field feedback, making it one of the most adaptable and service-friendly wrap-around case packers in its class.

Key Features

1 What Is a One-Piece Wrap-Around Case Packer?

A one-piece wrap-around case packer uses a single flat corrugated blank to wrap around a collated product group. The blank is pulled from a magazine, scored and folded around the products, then glued and compressed to form a finished shipping case. This design eliminates the need for separate case erecting and bottom-sealing stations, reducing floor space and mechanical complexity.

2 Core Advantages

3 Technical Specifications (Standard Model)

Experience, Expertise, Authoritativeness, and Trustworthiness

1 Experience – Proven in Demanding Production Environments

Wanying has been designing and manufacturing filling and packaging equipment since 2006. Our one-piece wrap-around case packer was developed in direct response to client requests for a simpler, more reliable alternative to multi-station case packaging lines. Over the past five years, we have deployed over 120 units of this model across juice dairies, condiment plants, and fermented bean curd facilities.Real-World Use Case 1 – Condiment Producer in GuangdongA medium-sized oyster sauce and peanut sauce manufacturer replaced their existing case erector + side-sealer combination with a single Wanying wrap-around case packer. Their previous line required three operators per shift and experienced frequent jams due to inconsistent blank feeding. After installation:

· Labor reduced from 3 to 1 operator per shift

· Case sealing failure rate dropped from 4.2% to 0.6%

· Floor space saved – 6.5 m² freed up for additional storage

· Production output increased by 18% without changing upstream filling speed

The client now runs two shifts daily, packing 480 mL glass bottles of oyster sauce in 2×3 cartons, with changeovers between sauce and vinegar lines completed in under 12 minutes.

2 Expertise – Engineered for Versatility and Durability

Our engineering team specializes in customized case handling solutions for liquid and semi-liquid food products. The wrap-around case packer's collating system is uniquely designed to handle both rigid containers (glass bottles, PET jars) and flexible packaging (stand-up pouches, doypacks) without damaging closures or seals.Key engineering choices that reflect our expertise:

· Dual-chain product infeed with adjustable lane guides ensures stable product spacing even with lightweight pouches

· Servo-controlled blank extraction prevents misfeeds common with pneumatic pick-and-place systems

· Overhead glue applicator with automatic nozzle cleaning reduces maintenance downtime to once per week

· All wear parts (chains, guides, forming plates) are hardened and replaceable without dismantling the main frame

3 Authoritativeness – Backed by Tier-1 Component Suppliers

As a factory that prioritizes quality at the component level, Wanying sources critical electrical and pneumatic parts exclusively from global leaders. Our partnership with Siemens (PLC and HMI), Omron (sensors and relays), Schneider Electric (circuit protection), and AirTAC (cylinders and valves) ensures that every wrap-around case packer meets international reliability standards.We also hold multiple technical patents related to case blank forming and product grouping mechanisms, which have been cited in industry publications on packaging automation.

4 Trustworthiness – Transparent Quality Assurance

Every Wanying case packer undergoes:

· 72-hour continuous run test with actual production blanks and product samples

· Glue bond strength test per ASTM D906 standard

· Electrical safety inspection (grounding, insulation, overcurrent protection)

· Full dimensional check using coordinate measuring equipment

We provide 24-month warranty on structural parts and 12-month warranty on electrical components, with remote diagnostics support available through our after-sales portal.

Key Components and Their Benefits

Installation & Operational Benefits

1 Space-Saving Footprint

The all-in-one design replaces the traditional three-machine combination (case erector + product loader + sealer). For plants with limited floor space, this is often the deciding factor in choosing wrap-around technology.

2 Lower Total Cost of Ownership

· Less mechanical complexity – fewer motors, conveyors, and sensors means lower spare parts inventory

· Simpler maintenance – all lubrication points are easily accessible; glue system cleaning takes under 10 minutes

· Energy efficiency – servo motors operate only on demand, reducing power consumption by approximately 25% compared to pneumatic-only systems

3 Flexible Integration

The packer can be integrated directly with:

· Upstream bottle unscramblers and fillers

· Downstream labeling machines, inkjet printers, and palletizers

· Centralized production management systems via Ethernet/IP or Profibus

Real-World Use Cases – Industry-Specific Applications

Use Case 2 – Dairy Processing Plant in Inner MongoliaA regional dairy producer packing 200 mL PET bottles of drinking yogurt needed to upgrade their manual case packing line. Their main challenges were:

· High labor turnover and training costs

· Inconsistent pack patterns causing case damage during palletizing

· Frequent downtime due to mismatched case sizes from different blank suppliers

Solution provided by Wanying:

· One-piece wrap-around case packer with servo-adjusted blank magazine

· Integrated product collation for 3×4 bottle patterns

· Recipe storage for three different bottle sizes (200 mL, 350 mL, 500 mL)

Results after 6 months:

· Packing speed increased from 12 to 26 cases/minute

· Case damage rate reduced from 5.1% to 0.3%

· Labor cost saved: ~¥180,000 annually

· ROI achieved within 10 months

Use Case 3 – Fermented Bean Curd Factory in HunanFermented bean curd (tofu) is a challenging product to package due to:

· Glass jars with fragile necks

· Residual brine that can wet case blanks

· Need for gentle handling to prevent product breakage

Solution:Wanying customized the case packer with:

· Extended product infeed length for slower, gentler lane merging

· Teflon-coated forming plates to prevent glue contamination from moisture

· Extra compression time for cases with heavier jar weights (up to 3 kg per case)

Outcome:

· Zero glass breakage reported over 3 months of operation

· Case compression quality improved, reducing returns from distributors

· Production line now runs unattended during second shift, monitored remotely via camera system

Use Case 4 – Purified Water Bottler in YunnanA medium-scale water bottler packing 550 mL PET bottles in 4×6 shrink-wrapped trays switched to corrugated cases to meet new retail requirements. They needed a case packer that could handle both shrink trays and full-wrap cases interchangeably.Wanying solution:

· Dual-mode operation capability with quick-change product grouping rails

· The same machine now runs wrap-around cases for supermarket orders and tray-only packs for wholesale accounts

· Changeover time: under 8 minutes

Frequently Asked Questions

Q1: What types of products and containers can the Wanying wrap-around case packer handle?

A: Our case packer is compatible with a wide range of rigid and semi-rigid containers, including:

· Glass bottles (all standard shapes) – suitable for sauces, fermented bean curd, juice

· PET bottles – for water, dairy drinks, and carbonated beverages

· Stand-up pouches – for condiments, liquid health products

· Cartons and paper cups – for instant food or dairy desserts

For unusual shapes or ultra-lightweight containers, we offer custom in-feed and collation designs to ensure stable handling without product damage.

Q2: How long does a format changeover take, and is it tool-free?

A: Standard format changeover (case size and product arrangement) takes 10–15 minutes using manual adjustments on guide rails and forming plates. Key adjustment points are equipped with handwheels and position indicators, so no tools are required for most changes. For clients who run multiple formats daily, we offer an optional quick-change frame with memory stops that reduces changeover to under 5 minutes.

Q3: What after-sales support does Wanying provide for this machine?

A: As a direct supplier, Wanying offers comprehensive after-sales support including:
