PP Hollow Sheet, also known as PP Corrugated Sheet, Corrugated Plastic Board, Polypropylene Hollow Sheet, PP Fluted Sheet, Correx, or Corflute, is a lightweight rigid sheet made from polypropylene. Its hollow fluted structure provides a useful balance of strength, weight, durability, and flexibility, making it suitable for packaging, advertising, printing, construction, agriculture, industrial products, and other applications.
As an experienced PP Hollow Sheet Manufacturer, Gokai supplies polypropylene corrugated sheets for distributors, packaging manufacturers, printing companies, advertising businesses, industrial users, and OEM buyers. Standard and customized sizes, different thicknesses, colors, densities, and surface treatments are available to meet different production and application requirements.
PP Hollow Sheet is an extruded polypropylene board with a hollow fluted structure. The internal flutes reduce material weight while maintaining useful rigidity and mechanical strength. Compared with many solid plastic boards, this construction can provide a more efficient material-to-weight ratio for applications where low weight and easy handling are important.
The non-porous polypropylene structure also provides resistance to water and moisture. Unlike paper-based packaging materials, PP Hollow Sheet does not readily absorb water, making it suitable for applications exposed to humidity, cleaning, transportation, or changing environmental conditions.
Gokai PP Hollow Sheet is available under model GK-PPHS and is produced for applications ranging from packaging and advertising to protection, construction, agriculture, and industrial use. The material can also be cut into customized shapes, printed, painted, and fabricated according to the requirements of the finished product.
The performance of PP Hollow Sheet comes from the combination of polypropylene material and its fluted internal structure. This makes it a practical alternative to conventional cardboard and some rigid sheet materials in many applications.
The hollow structure reduces unnecessary material weight while maintaining rigidity. This makes PP Hollow Sheet easier to transport, carry, process, and install.
For packaging manufacturers and businesses handling large quantities of products, lower weight can also help simplify storage and transportation.
Polypropylene is naturally resistant to water and moisture. PP Hollow Sheet can therefore be used in environments where conventional paperboard may soften, deform, or lose strength after exposure to moisture.
This characteristic is particularly useful for reusable packaging, agricultural packaging, floor protection, outdoor signage, and temporary construction protection.
PP provides good resistance to many common chemicals, oils, and corrosive substances. This makes PP Hollow Sheet suitable for selected industrial and packaging applications where the material may come into contact with moisture, cleaning agents, or other substances.
The actual chemical compatibility should be evaluated according to the specific chemical, concentration, temperature, and exposure time involved.
The fluted polypropylene structure provides useful impact resistance while keeping the board lightweight. PP Hollow Sheet can withstand repeated handling and is suitable for applications where packaging or display materials need to maintain their shape during transportation and use.
Its washable and reusable characteristics also make it suitable for returnable packaging systems and protective applications.
PP Hollow Sheet is made from polypropylene and can be recycled where appropriate recycling systems are available. Its smooth surface is also easy to clean, which is an advantage for reusable packaging, partitions, protection boards, and industrial applications.
PP Hollow Sheet can be cut into customized shapes and processed using suitable fabrication equipment. Its surface can also be used for printing with appropriate inks and printing processes.
For signage and advertising manufacturers, this allows the same basic sheet material to be converted into different graphic panels, promotional signs, display boards, and customized visual products.
Packaging is one of the major applications of PP Hollow Sheet. Its combination of low weight, moisture resistance, durability, and easy fabrication makes it suitable for reusable and protective packaging.
Gokai PP Hollow Sheet can be used for:
* Turnover boxes
* Bottle packaging
* Food packaging
* Fruit and vegetable packaging
* Gift boxes
* Partitions
* Mail boxes
* Display racks
* Dustbins
* Protective packaging
* Industrial product packaging
For manufacturers replacing disposable cardboard with reusable plastic packaging, PP Hollow Sheet provides a washable and durable alternative for selected applications.
It can also be fabricated into partitions and box components, helping separate products during transportation and reducing direct contact between packaged items.
The smooth surface of PP Hollow Sheet makes it suitable for a variety of advertising and graphic applications. It can be printed or processed into customized shapes according to the requirements of the final sign or display.
Common applications include:
* Advertising boards
* Real estate signs
* Election and political signs
* Event signage
* Indoor signs
* Outdoor signs
* Lawn signs
* Promotional displays
* Exhibition graphics
* Decorative display panels
For large-volume advertising campaigns, PP Hollow Sheet offers a practical combination of low weight, easy fabrication, printability, and cost efficiency.
Where printing performance is particularly important, Gokai can provide Corona-treated material within the specified width range to improve surface compatibility with suitable printing processes.
Beyond packaging and advertising, PP Hollow Sheet can also be used as a lightweight protection material in construction and interior applications.
Potential uses include wall protection, floor protection, temporary partitions, indoor and outdoor decoration, window protection, false ceilings, greenhouse roofs, and other temporary or semi-permanent structures.
Because the material is moisture resistant and easy to clean, it can be useful in environments where surfaces need protection from dust, dirt, water, or mechanical contact during construction or renovation.
Different applications require different combinations of thickness, density, dimensions, color, and surface treatment. Gokai provides standard PP Hollow Sheet specifications together with customized options for B2B buyers.
The standard thickness range is approximately 2–10 mm, while available sheet density varies according to thickness and product requirements. Standard sheet size includes 1220 × 2440 mm, with widths from approximately 600–2400 mm and lengths from 600–6000 mm available for suitable specifications.
Gokai also provides customized dimensions for buyers with specific fabrication or packaging requirements.
Color options include clear, transparent, red, blue, white, black, and other colors. This allows customers to match PP Hollow Sheet with different packaging systems, brand identities, signage designs, and visual applications.
For printing applications, Corona treatment is available within the applicable width range to improve surface printability.
The correct PP Hollow Sheet specification depends on how the material will be processed and used.
For lightweight advertising boards, thinner sheets may provide sufficient rigidity while keeping production and transportation efficient. For reusable packaging, partitions, floor protection, and applications requiring greater structural support, a thicker or higher-density sheet may be more appropriate.
Before placing an order, B2B buyers should consider:
* Required thickness
* Sheet density
* Panel dimensions
* Color
* Printing method
* Corona treatment requirements
* Cutting or die-cutting requirements
* Indoor or outdoor use
* Reusability requirements
* Packaging and transportation conditions
* Order quantity
Providing these details in advance allows the manufacturer to recommend a more suitable PP Hollow Sheet configuration and reduce unnecessary material adjustments during production.
