In the electronics industry, the film is used to package small components such as memory cards and SIM cards. Its anti - static properties prevent damage to the sensitive electronic components from electrostatic discharge, ensuring the reliability of the products during storage and transportation.

Agriculture

Greenhouse Films 

Natural - colored PP film is widely used in greenhouse agriculture. The film can effectively transmit sunlight, allowing plants to receive sufficient light for photosynthesis. At the same time, it has good heat preservation properties, which helps in maintaining a relatively stable temperature inside the greenhouse. In cold regions, the use of natural - colored PP film - covered greenhouses can extend the growing season of plants, enabling the cultivation of out - of - season vegetables and flowers.

For example, in tomato cultivation, the natural - colored PP greenhouse film provides an ideal environment for the growth of tomato plants. The film allows the right amount of sunlight to penetrate, promoting the healthy development of the plants. And during the night, the heat - retaining ability of the film reduces the temperature drop inside the greenhouse, protecting the plants from cold damage.

Mulching Films

 In addition to greenhouse applications, natural - colored PP film is also used as mulching film in open - field agriculture. The film can suppress the growth of weeds by blocking sunlight, reducing the competition for nutrients, water, and sunlight between weeds and crops. This helps in improving the yield and quality of agricultural products.

When used in the cultivation of watermelons, the natural - colored PP mulching film not only controls weeds but also conserves soil moisture. The film reduces the evaporation of water from the soil surface, ensuring that the watermelon plants have a stable water supply. This results in larger and sweeter watermelons.

Medical Field

Medical Packaging

In the medical field, the sterility and safety of medical products are of utmost importance. Natural - colored PP film is widely used in medical packaging due to its excellent barrier properties against bacteria, viruses, and other contaminants. It is used to package disposable medical devices such as syringes, needles, and surgical gloves.

The film's ability to maintain a sterile environment within the package ensures the safety of medical personnel and patients during use. For example, in the packaging of disposable syringes, the natural - colored PP film is carefully sealed to prevent any external contamination. The transparency of the film also allows medical staff to easily check the integrity of the syringe before use.

Wound Dressings 

Natural - colored PP film is also used in the production of wound dressings. The film is breathable, which allows the skin under the dressing to "breathe", reducing the risk of skin maceration. At the same time, it provides a protective barrier against external bacteria and other harmful substances. When used for treating minor cuts and abrasions, the natural - colored PP film dressing promotes the healing process by maintaining a clean and moist environment around the wound.

Construction Industry

Waterproofing Membranes

In the construction industry, natural - colored PP film is an important material for waterproofing. It is used in roofing, basement waterproofing, and other applications. The film's excellent waterproofing properties prevent water from penetrating into the building structure, protecting the building from water damage.

For example, in flat - roof construction, a layer of natural - colored PP waterproofing membrane is laid on the roof surface. This membrane can withstand long - term exposure to the elements, such as rain, snow, and sunlight. It effectively seals the roof, preventing water leakage and protecting the interior of the building from potential water - related problems such as mold growth and structural damage.

Insulation Materials

Natural - colored PP film can also be used in insulation materials. When combined with other insulating substances, such as fiberglass or foam, the film can enhance the overall insulation performance. The film acts as a vapor barrier, preventing the migration of moisture within the insulation layer. This helps in maintaining the insulation efficiency of the building over time.

In wall insulation systems, the natural - colored PP film - covered insulation panels provide better thermal insulation, reducing the energy consumption of the building for heating and cooling. This not only saves energy costs but also contributes to environmental protection by reducing the carbon footprint of the building.
