Import 5.5inch Calendar Case — Buy in Bulk from Supplier in China

The 5.5-inch calendar case from Sunshing Plastic Factory measures 9 x 126 x 142 mm and is constructed from polystyrene (PS), a rigid thermoplastic polymer known for dimensional stability and ease of moulding. The supplier bundles these cases in master cartons of 100 pieces, with intermediate bundling of 50 pieces per bundle, and each shipping carton occupies 45.7 x 26.5 x 29.6 cm. The compact form factor suits pocket, desk, or travel calendar formats rather than wall-hung variants.

PS material offers a Rockwell hardness of approximately M65 to M75 and a flexural modulus around 3.0 to 3.5 GPa, which gives the case sufficient rigidity for daily handling without the cost of engineering plastics such as ABS or polycarbonate. Standard PS is naturally transparent but can be tinted or opacified; the listing does not specify colour or surface finish, so buyers should confirm whether the material is general-purpose crystal PS or a modified high-impact grade. Typical calendar cases in this segment use virgin PS rather than recycled regrind to avoid stress-cracking at hinge points.

Corporate gift distributors, educational suppliers, and retail stationery chains represent the core buyer segments for this SKU. The flat, slim profile accepts screen printing or pad printing for branding, though the maximum printable area and colour registration tolerances are not stated and should be requested from Sunshing Plastic Factory. Import buyers should verify whether the supplier holds any colour-fastness or migration test reports, especially for promotional items intended for EU or North American markets where EN 71-3 or CPSIA compliance may be required.

Sunshing Plastic Factory is located at No.15 Jinhu Road, Jinhu Industry Area, Chenjiang Town, Huizhou, Guangdong Province, China, placing it within the Pearl River Delta manufacturing cluster. The supplier is classified as "imported" tier with a "harbor" trust tier, and both response rate and average response hours register at zero, which indicates no recent inquiry activity or that response metrics are not being captured. Buyers should treat direct communication as essential rather than relying on platform-reported responsiveness.

The supplier profile does not disclose year of establishment, employee count, factory floor area, revenue, or clientele. No certifications such as ISO 9001, ISO 14001, or BSCI are mentioned. The listing presents only the calendar case and does not indicate whether Sunshing operates as a dedicated moulding facility or a broader stationery converter. Buyers should request a factory profile, current production capacity in moulds per month, and any existing export reference markets before committing to an order.
