| Tube Inner Diameter | 30–90 mm
Defined by the bottle, insert, or secondary packaging. | Specify the actual product diameter plus the required clearance. Confirm whether the tube holds one bottle, a bottle with an insert, or a complete gift set. | An incorrect inner diameter can cause movement, difficult insertion, or excessive pressure on the glass bottle. | Measure the packed product at its widest point and approve a physical fit sample before mass production. |
| Tube Height | 70–220 mm
Commonly matched to perfume bottles and discovery sets. | Define the usable internal height, lid overlap, base clearance, and any allowance required for an insert or cushion. | Height affects product protection, visual proportion, pallet efficiency, and shipping volume. | Measure the complete packed height and check lid closure, internal clearance, and overall presentation. |
| Wall Thickness | 1.0–3.0 mm
Varies with paperboard layers and required compression resistance. | Use a thicker wall for heavier glass bottles, premium gift sets, long-distance transport, or high stacking loads. | Wall thickness influences rigidity, edge protection, compression performance, and perceived quality. | Record the agreed tolerance and perform compression and drop testing on the finished tube. |
| Paperboard Structure | Spiral-wound or convolute-wound paper tube with paperboard body and separate or integrated components. | Choose a structure that balances stiffness, surface smoothness, decoration requirements, and recyclability goals. | Different winding structures affect dimensional accuracy, seam appearance, strength, and production cost. | Request a construction diagram or cross-section sample showing the body, shoulder, base, and lid layers. |
| Material Recycled Content | Declared percentage
May vary by paper grade and supplier sourcing. | State the minimum recycled-content percentage required by the project and request supporting documentation when environmental claims are used. | Material content affects sustainability communication, appearance, strength, and eligibility for certain customer policies. | Review the material declaration, paper specification, and any applicable chain-of-custody documentation. |
| Surface Finish | Uncoated, matte coating, gloss coating, soft-touch coating, or textured paper wrap. | Select the finish according to the desired tactile effect, scratch resistance, ink appearance, and recycling requirements. | Fragrance packaging is frequently handled at retail and during fulfillment, so surface durability affects its appearance. | Approve a color-and-finish sample under consistent lighting and conduct rub and scratch checks. |
| Color Reproduction | Defined by an approved color reference and production tolerance. | Provide a physical color reference or a recognized color standard, and define whether the result is solid, metallic, gradient, or textured. | Paper absorbency, coating, and printing method can change color appearance compared with a digital design file. | Approve a printed proof or production sample rather than relying only on screen colors. |
| Decoration Method | Offset printing, flexographic printing, digital printing, foil stamping, embossing, debossing, or labeling. | Choose the method based on order volume, artwork detail, metallic effect, tactile requirements, and required registration accuracy. | Decoration choices affect minimum order quantities, tooling, lead time, cost, and the final visual hierarchy. | Confirm artwork dimensions, bleed, safe area, foil or embossing depth, and approval sample requirements. |
| Closure and Lid Fit | Slip-fit lid, shoulder lid, telescopic lid, friction-fit closure, or magnetic-assisted presentation structure. | Specify opening force, lid overlap, anti-loosening requirements, and whether the lid must remain secure during export shipment. | A closure that is too loose can open in transit; one that is too tight can damage the tube or reduce usability. | Carry out repeated opening-and-closing checks and test the packed tube after vibration or drop exposure. |
| Bottle Retention | Paperboard insert, molded-pulp insert, cardboard partition, foam alternative, or precision-fit interior. | Use an insert when the bottle has clearance inside the tube or when the product requires extra protection against impact and movement. | Retention prevents rattling, reduces impact transfer, and helps keep the product centered during transport. | Test the complete set in its final orientation and check movement after repeated handling. |
| Barrier and Moisture Protection | Uncoated paper structure or paper structure with a functional coating or inner barrier. | Define whether the tube is only secondary packaging or must tolerate elevated humidity, condensation, or contact with oily surfaces. | Paperboard can lose stiffness when exposed to moisture, which may affect dimensional stability and surface quality. | Specify the intended storage and transport environment, then conduct humidity or conditioning tests when necessary. |
| Odor and Product Compatibility | Low-odor packaging materials with no unwanted transfer to the fragrance presentation. | Require material samples to be checked for residual odor, ink odor, coating odor, and compatibility with the packed fragrance format. | Unwanted packaging odor can interfere with the consumer’s fragrance experience, especially when the package is opened close to the product. | Evaluate the empty tube and packed tube after conditioning in a clean, odor-controlled area. |
| Drop and Compression Performance | Test level based on package weight, distribution method, stacking pattern, and destination conditions. | Define the packed weight, drop orientation, stacking duration, and acceptance criteria before testing. | Protection requirements differ between retail handling, parcel delivery, palletized freight, and mixed-load export shipping. | Test the final production-equivalent package, not only an empty tube or a laboratory mock-up. |
| Dimensional Tolerance | Commonly agreed by component and manufacturing process; tighter tolerances may require additional controls. | Set tolerances for diameter, height, lid fit, insert position, print registration, and component alignment. | Clear tolerances reduce disputes and ensure that the bottle, insert, and tube work together consistently. | Use a calibrated measurement method and define the sample size and inspection level in the purchase specification. |
| Flat-Pack or Assembled Delivery | Rigid assembled tube or partially assembled component set. | Select assembled delivery when shape protection and fast packing are priorities; consider component delivery when logistics volume is critical. | Packaging format affects storage space, freight efficiency, assembly labor, and the risk of deformation. | Compare cubic volume, assembly time, handling damage, and total landed cost for both options. |
| Carton and Pallet Requirements | Export carton dimensions, gross weight, carton quantity, pallet pattern, and labeling defined per shipment. | Specify maximum carton weight, carton marking language, pallet dimensions, stacking limits, and moisture protection for the destination. | Transport packaging affects warehouse handling, freight utilization, customs processing, and damage rates. | Approve a packing specification showing inner quantity, carton quantity, gross weight, dimensions, and shipping marks. |
| Regulatory and Sustainability Claims | Claims must be supported by the applicable market rules and documented material information. | Define required statements such as recycled content, recyclability, paper source, or disposal guidance before artwork approval. | Environmental and packaging claims may require evidence and may be interpreted differently across destination markets. | Review claim wording with the responsible compliance team and retain supporting declarations for the shipment. |
| Sampling and Approval Gates | Structural sample, printed proof, pre-production sample, and final production inspection. | Do not release mass production until dimensions, fit, color, finish, closure, insert, and packing method are approved. | Early approval gates reduce the risk of expensive corrections after tooling, printing, or international shipment. | Use a signed specification sheet with reference samples, measurable tolerances, and documented acceptance criteria. |
| Commercial Planning Data | Target quantity, annual forecast, tooling needs, sampling cost, production lead time, and replenishment schedule. | Provide the expected first order, repeat order frequency, peak-season demand, and required delivery window. | Volume and forecast affect material purchasing, printing setup, production scheduling, inventory, and landed cost. | Request a quotation that separates tooling, sampling, unit price, packaging, freight assumptions, and lead time. |
