Waterproof and oil-proof Off-white HDPE gloves

Waterproof and oil-proof, these white HDPE gloves are widely used in household cleaning, food processing, beauty salons, gardening machinery, laboratory testing, and industrial and agricultural protection. For example, when handling greasy ingredients in the kitchen, they can effectively prevent grease from staining your hands; in chemical laboratories, they can prevent chemicals from corroding your skin; when cleaning at home, they can prevent the spread of stains and bacteria. In addition, these gloves are also suitable for outdoor camping, barbecues, and other scenes, providing users with comprehensive protection.

Product Advantages

Material and Technology:

● Made of new HDPE raw material, it has high transparency and durability. The surface is specially processed with concave and convex processing, which is non-slip and easy to wear.

● Functionality: It has the functions of waterproof, oil-proof, anti-bacterial and acid-alkali resistant, suitable for a variety of harsh environments. It does not contain natural latex ingredients and has no allergic reaction to the skin.

● Design and Comfort: The gloves are of moderate thickness (1.0-3.5 silk) and fit the hand shape. They provide good flexibility and grip and are suitable for long-term wear.

● Environmental protection and economy: Disposable use, avoid cross contamination, conform to the concept of environmental protection, and are affordable. They are the preferred choice of general economic protective gloves.

Technology and craftsmanship

1. Core production process

‌Raw material ratio and pretreatment‌
PE gloves are mainly made of LDPE (low-density polyethylene), HDPE (high-density polyethylene) or LLDPE (linear low-density polyethylene) raw materials, which are mixed with additives (such as plasticizers and anti-sticking agents) to form a homogeneous material. Some processes introduce composite modification technology to improve barrier properties (such as oil resistance and chemical resistance).

Film blowing
molding: After the mixed raw materials are melted at high temperature in a blow molding machine, they are extruded through a ring die to form a tubular PE film. The film thickness is controlled by air pressure and traction speed, and the thickness accuracy can reach ±0.01mm^[2][8]. The film blowing technology directly determines the uniformity and mechanical properties of the gloves.

‌Mold hot pressing molding‌
uses a reciprocating finger mold to hot press the PE film. The mold temperature is controlled at 120-150℃, the pressure is about 0.5MPa, and the molding time is 0.5-1 second, which can achieve rapid separation of disposable gloves. The automated mold system can achieve a pressing efficiency of 200-300 gloves per minute.

‌Separation and Packaging‌
The formed gloves are automatically separated from the waste by pneumatic grippers, and the defective products are removed by the visual inspection system. Before packing the qualified products, triple packaging (plastic film + box + outer box) is carried out to ensure hygiene and safety.

2. Key technical improvements

● ‌Anti-slip structure design‌ : Adding pitting or texture on the mold surface increases the friction coefficient of the gloves and improves the anti-slip performance by more than 40% (laboratory test data).

● Process energy saving optimization‌: Using low-temperature film blowing technology (melting temperature reduced by 15°C), energy consumption is reduced by 20% while avoiding material degradation.

● ‌Waste recycling system‌: The recycling ratio of scraps after crushing reaches 30%, reducing the raw material cost by 10%-15%.

3. Performance indicators and quality control

● Physical properties: tensile strength ≥8MPa, elongation at break ≥300% (GB/T 1040.3 standard);

● ‌Chemical protection‌: Passed 24-hour 10% salt water immersion test, water permeability <2.1g/m²·24h;

● Hygiene Control: The production environment complies with ISO 14644-1 Class 8 cleanliness requirements, and the finished products are sterilized with ethylene oxide.

4. Application adaptability analysis

● ‌Low-cost scenarios‌: The cost of a single PE glove is about 0.02 yuan, which is suitable for light-load scenarios such as catering sorting and short-term cleaning;

● Limitations: The upper temperature limit is 60°C. It is easily damaged when exposed to organic solvents or sharp objects. It is not suitable for medical surgery and other fields with high protection requirements.
