Waterproof and oil-proof Off-white LDPE gloves

 1. Application scenarios‌

Catering Industry‌

● PE gloves are widely used in the catering industry because of their low price and easy availability. They are suitable for handling foods with low oil content, such as fruits and vegetables.‌However, PE gloves are not suitable for long-term contact with high-fat foods or doing housework.‌

● Family life‌PE gloves are widely used in daily life at home because of their lightness and easy to carry. For example, handling food, cleaning housework, etc.‌

● Industrial and Manufacturing‌: In industry and manufacturing, PE gloves are often used to handle chemicals, perform simple assembly work, etc. Their low cost and easy shaping properties make them have a high market share in these fields‌.

● Agriculture‌: In the agricultural field, PE gloves are used for handling soil, planting crops, etc., and are popular because of their durability and low cost.‌

● Medical Industry‌: Although PE gloves are not as widely used in the medical field as TPE gloves, they are still used for some basic medical operations, especially when handling non-corrosive drugs.

Product features and advantages:

● Waterproof, oil-proof, bacteria-proof, acid-resistant and alkali-resistant‌ PE gloves have these basic characteristics and can effectively protect users from oil and chemical substances.‌

● Low cost‌ The raw materials of PE gloves are mainly low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE). These materials have low costs, which makes PE gloves have obvious advantages in price.‌

● Easy to shape‌: PE gloves are easy to process and shape, suitable for large-scale production and application‌.

● Wide range of application scenarios‌: PE gloves are widely used in catering, medical, industrial and other fields. For example, in the catering industry, PE gloves still occupy 65% of the market share due to their low cost and good protective performance.‌

 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).‌

Blown Film‌

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

The PE film is hot-pressed using a reciprocating finger mold, the mold temperature is controlled at 120-150°C, the pressure is about 0.5MPa, and the molding time is 0.5-1 second, achieving 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 defective products are removed by the visual inspection system. Before packing qualified products, triple packaging (plastic film + box + outer box) is performed to ensure hygiene and safety.

● Anti-slip structure design‌: Adding pitting or texture to the surface of the mold can increase the friction coefficient of the gloves and improve 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 proportion of scraps after crushing is up to 30%, reducing the cost of raw materials by 10%-15%.‌Physical properties‌ : Tensile strength ≥8MPa, elongation at break ≥300% (GB/T 1040.3 standard);

● Chemical protection‌: Passed the 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.

● Low-cost scenario‌: 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;

● limitation‌: The upper temperature limit is 60℃. It is easy to be damaged when it comes into contact with organic solvents or sharp objects. It is not suitable for areas with high protection requirements such as medical surgery.
