Jiangyin Ruihesheng Paper Products Co., Ltd. has manufactured eco-friendly paper-based packaging for the food and catering industry from our Wuxi, Jiangsu base since 2004. The octagonal paper bowl and box family sits inside our paper bowl and cup range, alongside general paper bowls, liquid paper buckets, noodle bowls and square bowls. We build the format from 300 ml to 1200 ml with matched closures, in kraft or white board, plain or printed, and we cut tooling around the fill volume and lid interface rather than forcing a stock size onto the application.
Our Octagonal Paper Bowl/Box Range
The eight-sided profile is a structural decision, not a decorative one. Flat panels and folded corner geometry produce a wider standing base and a rim that resists ovalising when the bowl is lifted under load, and they give eight printable faces so artwork reads from any angle on a shelf or counter. We supply the range as a complete bowl-and-lid system, so rim profile, closure and stacking height are matched at the tooling stage.
| Format | Bowl profile | Typical food applications | Closure pairing |
|---|---|---|---|
| 300 ml | Recyclable octagonal bowl, compact base | Dips, condiments, tasting portions, small sides | Paper lid |
| 400 ml | Shallow-profile octagonal snack bowl and pastry box | Pastries, cookies, small bakes, dry snacks | Paper lid or board cover |
| 500 ml | Compact octagonal dessert and snack bowl | Desserts, ice cream, fruit, yoghurt | Paper lid or clear lid |
| 650 ml | Wide-mouth kraft layered salad bowl | Salads, grain bowls, poke, cold deli | Flat paper lid or clear lid |
| 750 ml | Strong and durable octagonal bowl | Hot rice, noodles, curries, takeaway mains | Paper lid |
| 1000 ml | Light and convenient octagonal box bowl | Family portions, meal prep, sharing dishes | Paper lid |
| 1200 ml | Square kraft food container | Sharing portions, cold deli, catering trays | Clear lid |
Formats above 1000 ml are normally specified for sharing and catering rather than single-serve, and we adjust board weight and rim depth to suit the fill weight and the way the pack is carried. A representative build is the 750 ml strong and durable octagonal paper bowl, which we configure for hot mains where rim stiffness matters most.
Board, Barrier and Coating Options
Our standard route uses FSC-certified board and post-consumer recycled pulp, without PE or PLA plastic coating. Where grease or moisture resistance is required we apply an algae-barrier coating route supported by TÜV industrial composting certification, and we run water-based and plant-based inks, biodegradable labels and adhesives through the print and finishing stages.
- Board grades: kraft or white, coated or uncoated, selected against fill weight and expected holding time.
- Barrier: uncoated for dry bakery and snack items; algae-barrier coating for oily, saucy and moist foods.
- Temperature: board grade and rim seal are confirmed against the actual serving temperature rather than a generic hot or cold label.
- End-of-life: plastic-free construction keeps the bowl in the paper recycling stream where local infrastructure accepts food-contact board.
Printing and Surface Finishing
Flexographic and UV printing lines cover both high-volume plain work and branded runs. Single-sided and double-sided printing are available with spot-colour or four-colour process work, and the finishing line handles hot stamping, partial UV, embossing and laminating.
- Artwork is checked against the die layout before plates are cut, so panel breaks and corner folds do not fall across logos or text.
- Food-contact surfaces are kept clear of finishes that would compromise the barrier.
- Colour targets are agreed against a physical proof or press sample before the run starts.
Structural Configuration and Lid Pairing
Configuration starts with the working point: nominal fill volume, headspace, food type and how the bowl is handled. From there we set rim diameter, wall height, base diameter and board weight, then match the closure to the application.
- Paper lid — the default for hot mains, noodles and rice; a same-material closure keeps the pack mono-material.
- Board cover — used on shallow snack and pastry formats where a low-profile closure is preferred.
- Clear lid — specified for cold deli, salad and dessert presentation where contents need to be visible.
- Venting and nesting — vent slots for steamed hot food, and nesting geometry tuned so filled bowls stack without jamming on a filling line.
Production Flow and In-Process Control
Every octagonal bowl follows the same ten-stage route through our 15,000 m² facility, which runs more than 100 automated machines across paper boxes, cups, bowls, corrugated containers and multi-compartment trays.
- Raw material procurement — pulp, laminating materials and ink.
- Raw material inspection against production standards.
- Paper cutting to the required web and blank size.
- Die-cutting and forming of the basic structure.
- Printing by flexographic or UV process.
- Die-cutting and moulding into the finished shape.
- Bonding, folding and assembly.
- Finished-goods inspection of dimensions, strength and print quality.
- Packing of qualified product.
- Warehousing, order allocation and logistics.
Incoming board, in-process forming and finished goods are each inspected, and the procedural controls keep quality traceable from batch to batch across repeat orders.
Compliance, Acceptance and Documentation
We are certified to ISO9001, ISO22000, FSC, BRC and SGS, and hold SABER, SYDEX, IAF and CNAS accreditations. Product ships to the USA, France, Sweden, Japan, South Korea, Singapore and other markets, so the documentation set is assembled against the destination market rather than issued as one generic pack.
- Material and food-contact declarations for the board, coating and ink system.
- FSC chain-of-custody references where certified fibre is specified.
- Dimensional and strength records from the finished-goods inspection stage.
- Pre-shipment samples for approval before mass production.
Information We Use to Configure Your Solution
A quotation is only useful when it matches the working point. These are the inputs that let us fix bowl, lid, print and packing specification without a round of guesswork.
| Project input | What we need | What it determines |
|---|---|---|
| Capacity | Nominal fill in ml plus headspace | Bowl depth, rim diameter and base diameter |
| Food contact | Hot, cold, oily, saucy or high-fat | Board grade and barrier route |
| Closure | Paper lid, board cover or clear lid | Rim profile and closure tooling |
| Artwork files, colour references, coverage | Flexo or UV route, plate count, finishing | |
| Packing | Units per sleeve, carton and pallet | Carton board grade and pallet pattern |
| Compliance | Destination market and labelling rules | Documentation and declaration set |
| Volume and schedule | First order and repeat pattern | Tooling plan and line allocation |
Packing, Delivery and Repeat Supply
Bowls are nested and sleeved, then cartoned to an agreed count with a pallet pattern that suits the receiving warehouse. Carton board grade, sleeve labelling and pallet height are fixed with the order, and the same specification is held for repeat runs so a reorder does not restart the tooling conversation.
OEM and ODM work is part of our standard service: we handle structural design and rendering, produce samples for approval, and carry the specification through to mass production. Annual capacity runs to several billion units, which supports both launch volumes and ongoing programme supply. As an Octagonal Paper Bowl/Box manufacturer, we keep the bowl, lid and print specification on one record from sampling through to delivery.
Frequently Asked Questions
Which sizes does the octagonal paper bowl range cover?
We produce 300 ml, 400 ml, 500 ml, 650 ml, 750 ml, 1000 ml and 1200 ml formats, and we cut custom dimensions where the fill volume or the filling line requires a non-standard rim or depth.
Can an octagonal paper bowl hold hot, oily or saucy food?
Yes, provided the board grade and barrier are matched to the food. For oily and saucy dishes we specify the algae-barrier coating route rather than an uncoated board, and we confirm the combination against the actual serving temperature and holding time.
Which lids fit the octagonal bowl?
Paper lids, board covers and clear lids are all available. The rim profile is set at tooling stage for the chosen closure, so a lid specified later is matched to the same rim rather than fitted by tolerance.
Can we print our own artwork on the bowl?
Flexographic and UV printing support single-sided and double-sided decoration, spot-colour or four-colour process work, plus hot stamping, partial UV, embossing and laminating. We check artwork against the die layout before plates are produced.
What certifications and declarations apply to the octagonal range?
Our operations are certified to ISO9001, ISO22000, FSC, BRC and SGS, with SABER, SYDEX, IAF and CNAS accreditations. FSC-certified board, plant-based and water-based inks, and the TÜV industrial composting algae-barrier route are available on this range.
What do you need from us to prepare a quotation?
Fill volume and headspace, food type and serving temperature, preferred closure, artwork or a design brief, packing counts, destination market and the first-order volume with the expected repeat pattern. With those inputs we can return a bowl, lid, print and packing specification ready for sampling.
