How Can Cooling Powder Be Packed as a Twin-Pack Promotion While Preserving Product Information and Shelf Appeal?
Converting bottled cooling powder from single units into a twin-pack promotion involves more than simply grouping two bottles together. The packaging process must account for bottle tilting, twin-bottle alignment, stable product handling, seal-line positioning, POF shrink film performance, and heat shrinking conditions to achieve reliable production and a clean appearance.
This project was developed for a Thai company seeking an automated twin-pack solution for bottled cooling powder. The existing line fed bottles in an upright position, while the new requirement was to combine two bottles into one promotional pack using printed POF shrink film for both product presentation and promotional communication.
After evaluating bottle geometry, infeed orientation, twin-pack configuration, product information placement, and shrink requirements, Benison engineered an integrated solution combining automatic bottle tilting, twin-bottle alignment, a side-seal horizontal flow wrapping machine, and a window-type heat shrink tunnel. The result is a complete automated packaging process designed around the customer’s actual product and production conditions.
How Should a Cooling Powder Packaging Line Be Reconfigured from Single Bottles to Twin Promotional Packs?
The key to twin-pack promotional packaging is converting individually fed bottles into accurately aligned pairs before they enter the downstream shrink wrapping.
Manual bottle tilting and pairing can increase labor requirements and create inconsistencies in bottle orientation, spacing, and alignment that affect packaging. Benison therefore started with the customer’s existing upright infeed conditions and redesigned the process around the actual product, integrating bottle tilting, twin-bottle alignment, side sealing, and heat shrinking into a coordinated automated packaging line.
▍Packaging Challenges
This project involved three primary packaging challenges:
- Twin-Pack Configuration for Cooling Powder: The cooling powder bottles were originally conveyed upright, but twin-pack packaging required a change in product orientation. Because the bottles have curved surfaces, horizontal handling also had to address rolling, shifting, spacing between the two bottles, and stable transfer into downstream equipment. The orientation-change and alignment method therefore required a purpose-designed solution.
- Keep the Seal Line Away from Product Information: The bottles already carried brand names, product descriptions, and visual graphics. If the POF film seal line crossed the primary display panel, it could reduce readability and compromise package appearance. The seal position therefore had to be coordinated with twin-bottle alignment and the location of key information on the bottle.
- Printed POF Film for Promotional Communication: In addition to securely grouping two bottles, the promotional pack needed to communicate campaign information on the outer packaging. The selected packaging material therefore had to balance print quality, shrinking performance, product visibility, and external protection.
▍Benison's Packaging Solution
To address these requirements, Benison evaluated the complete process from product infeed through the finished shrink packaging. The integrated line includes:
- Automatic bottle tilting unit
- Twin-bottle alignment and transfer
- Side-seal horizontal flow wrapping machine with window-type heat shrink tunnel
- Printed POF heat shrink film
By integrating the packaging and shrinking process, upright single bottles can proceed through orientation change, twin-bottle alignment, side seal flow wrapping and shrinking with reduced manual sorting and handling between processes.
How Can Upright Cooling Powder Bottles Be Converted into Stable Twin-Pack Alignment?
Based on the twin-pack packaging requirements, Benison evaluates the product shape, infeed orientation, twin-pack configuration, and packaging conditions to develop an integrated solution that converts individual cooling powder bottles into stable twin-pack groups. The solution is customized according to product dimensions, bottle characteristics, pack quantity, and required production capacity.

Why Is Side-Seal Flow Wrapping Used for Twin-Pack Cooling Powder?
Because the bottles already display brand names and product information, Benison uses a side-seal flow wrapping configuration that positions the primary seal line along the side of the twin pack. This minimizes interference with the main display panels, keeps product information easier to read, and supports a cleaner, more consistent appearance after heat shrinking.
How Can Printed POF Shrink Film Support Both Product Protection and Promotional Display?
Printed POF heat shrink film groups two cooling powder bottles into a promotional pack while providing dust, moisture, and external protection. The printed surface can carry promotional messages for stronger retail communication. Combined with side-seal flow wrapping, the solution preserves visibility of the original bottle information while supporting brand presentation and an attractive promotional multipack format.
From bottle orientation through the finished twin shrink pack, each stage is configured around the actual product and packaging requirements, helping manufacturers balance automation efficiency, product presentation, and promotional packaging objectives.
What Are the Advantages of This Packaging Line?
This solution is engineered around the customer’s existing upright single-bottle infeed. Automatic bottle tilting and twin-bottle alignment reduce manual placement, pairing, and sorting, while the side-seal flow wrapping and shrink process creates an integrated automated line from individual bottle infeed to finished twin-pack bundling.
The side-seal design keeps the primary seal line away from key bottle information and brand graphics. Combined with printed POF shrink film and a window-type shrink tunnel, the solution supports clean package appearance, promotional visibility, dust and moisture protection, and controlled shrink quality in a complete automated twin-pack packaging system.
Suitable Applications
Beyond cooling powder, this automatic bottle tilting, twin-alignment, side-seal flow wrapping solution can be evaluated for products such as:
- Personal care products: prickly heat powder, cooling powder, lotions, and bottled cleansing products
- Beauty and skincare products: bottled skincare products and twin-pack promotional sets
- Household products: bottled cleaners, household goods, and multi-bottle bundles
- Promotional multipacks: twin packs, bundled packs, and other multi-item promotional packaging formats
Actual suitability should be verified through testing based on product dimensions, weight, surface characteristics, packaging material, and production conditions.
▍Frequently Asked Questions (FAQ)
- Why Use Side-Seal Flow Wrapping for Twin-Pack Cooling Powder? Shrink flow wrapping allows POF film to conform neatly around the twin pack, while the side-seal configuration positions the primary seal line along the side of the product. This helps minimize interference with brand names, product descriptions, and the main display panel, preserving both information visibility and overall package appearance.
- Will Cooling Powder Products Be Affected by Heat in the Shrink Tunnel? Different products, bottle materials, and packaging films respond differently to heat shrink conditions, so actual sample testing is required. Benison determines suitable shrink settings based on the product, bottle material, POF film, and equipment configuration rather than applying a fixed temperature to every application.
- Can Promotional Information Be Printed on POF Shrink Film? Yes. This project uses printed POF shrink film to combine and protect the two bottles while displaying promotional information on the outer pack. This gives brand owners an additional communication surface and can improve product recognition and promotional visibility at retail.
