Wholesale Straw Cosmetic Bottle Manufacturers

What are the environmental advantages of straw cosmetic bottles?

What is the environmental value of straw cosmetic bottles?
1. Utilize agricultural waste and regenerate resources
Straw is a large byproduct produced in the agricultural production process. Traditional treatment methods are mostly incineration or landfill, which not only causes environmental pollution but also wastes renewable resources. The raw materials of straw cosmetic bottles are partly derived from rice husk fibers. Through composite processing with renewable plastics such as polypropylene (PP) or polyethylene (PE), resources are effectively recycled. This bio-based composite material not only reduces dependence on traditional petroleum-based plastics, but also gives waste straw new commercial and ecological value.
2. Reduce carbon footprint and energy consumption
Straw plastics require less energy consumption in the production process than traditional all-plastic materials, and their life cycle carbon emissions are relatively small. Shaoxing Roman Plastic Co., Ltd. has further optimized the processing energy efficiency of straw materials by introducing efficient injection molding equipment and improved heating systems to ensure high-quality output under the concept of environmental protection.
3. Promote packaging degradation and recyclability
Although straw plastic itself is not completely biodegradable, its composite structure improves the decomposability of the product under natural conditions. In addition, the straw bottle design adopted by Roman Plastic emphasizes simple structure and single material system, which is convenient for consumers to sort and recycle after use. In addition, the company also customizes reusable and detachable bottle designs for customers to help brands achieve the goal of "zero waste packaging".
Roman Plastic's environmental protection strategy and technical strength
Founded in 2016, Shaoxing Roman Plastic Co., Ltd. is located in Shangyu, Zhejiang, adjacent to Ningbo and Shanghai ports, covering an area of ​​13,000 square meters. The company currently has more than 50 injection molding machines and more than 15 assembly and packaging production lines, with an annual export volume of approximately US$4 to 5 million, and its business covers many countries and regions such as the United States, Germany, Australia, Canada, New Zealand and the Middle East.
As a cosmetic packaging solution provider integrating design, manufacturing and testing, Roman Plastic has been committed to promoting the research and development and practical application of environmentally friendly materials. In the straw cosmetic bottle project, the company not only participated in the research on raw material ratio and modification, but also combined mature surface treatment processes (such as spraying, UV coating, silk screen, hot stamping, etc.) to make environmentally friendly materials comparable to traditional plastic bottles in terms of beauty and durability.

From product structure design to mold development, from sample proofing to mass production, Roman Plastic provides one-stop services to help brands transform green concepts into market competitiveness.

What are the precautions for the storage of straw cosmetic bottles

Characteristics and potential impacts of straw materials
The main raw material of straw bottles is processed natural rice husk fiber, which is usually mixed with recyclable plastics such as PP (polypropylene) for injection molding. Although this composite material has good strength, texture and environmental advantages, it also has the following physical properties that need attention:
High hygroscopicity: Natural plant fibers have a certain degree of hydrophilicity and are prone to moisture absorption and expansion in a high humidity environment;
Temperature sensitivity: Composite materials may deform or lose strength under high temperature or sudden cooling conditions;
Limited surface coating stability: If there is UV coating, spray painting or silk screen printing process, it is easy to fade and bubble under improper lighting or temperature and humidity fluctuations.
Therefore, from raw material safety to product beauty, from functional stability to customer experience, the storage management of straw bottles needs to be more professional and systematic.
Professional storage precautions for straw cosmetic bottles
1. Avoid high temperature and direct sunlight
Straw composite materials may soften or deform slightly under continuous high temperature (such as ≥50°C), especially bottles that are not fully filled or have thinner structures are more sensitive. Therefore, straw cosmetic bottles should be stored in a cool and ventilated place, avoiding direct sunlight and close to heat sources (such as heating pipes and hot air outlets).
Shaoxing Roman Plastic Co., Ltd. stipulates in its warehouse management that all straw bottles should be stored in a constant temperature warehouse with a temperature control range of 15°C~30°C to protect the product structure and surface treatment quality to the greatest extent.
2. Control humidity and avoid humid environment
High humidity environment may cause rice husk fiber to absorb water and swell, thus affecting the dimensional accuracy of the bottle and the sealing of the cap. It is recommended to store straw bottles in a dry environment with a relative humidity not exceeding 65%, and use a dehumidifier or moisture-proof bag for auxiliary treatment.
Roman Plastic helps customers effectively control humidity during transportation and storage by adding desiccant and moisture-proof film to the packaging box to ensure the stability of the product.
3. Avoid heavy pressure and stacking too high
Although straw bottles have good mechanical strength, they still have the risk of collapse or deformation of the bottle mouth under excessive pressure, especially when the empty bottle is not supported. It is recommended that customers stack no more than 5 boxes per layer during storage, and use special pallets and pressure-resistant cartons for classification and stacking.
Roman Plastic's packaging design is customized for environmentally friendly materials and adopts a multi-layer buffer structure to ensure that the bottle is not squeezed during transportation and storage.
4. Avoid cross-contamination of odors
Straw-based materials are more sensitive to odors and easily absorb odorous substances in the surrounding environment. They should be stored away from strong-smelling items such as paints, detergents, and fragrance raw materials to avoid affecting the odor of the bottle and the quality of the filled cosmetics.
As a company with multiple dust-free packaging lines, Shaoxing Roman Plastic Co., Ltd. has an odor detection process in both production and warehousing to prevent cross-contamination and maintain product purity.
