EXPERIENCE YOU CAN RELY ON
Hygiene and personal care products are subject to the highest requirements in terms of safety, reliability, discretion, and innovation. With decades of experience in designing, developing, manufacturing, and supplying high-performance barrier film solutions for personal care products – from newborn to old, SUNREE is one of the most trusted partners in the personal care field.
Our portfolio for personal care includes cast and blown PE film, textile back sheet, perforated film, and biodegradable film, which provide thin yet durable, tough yet discreet, maximum protection and comfort.
PRODUCTS
Our backsheet film, topsheet film, and pouch film for disposable baby diapers, feminine sanitary pads, pantyliners, adult incontinence diapers, and underwear, and underpads allow converters and brand owners confidence in the quality, performance, and reliability of their products.
Breathable PE Film features a microporous structure that allows water vapor to pass through while preventing liquid water from penetrating. It provides excellent breathability, enhances user comfort, and allows the skin to breathe more freely. As a result, it helps minimize the risk of skin irritation, rashes, sores, and other related discomforts.
Non-breathable PE Film is produced from a blend of polyethylene using extrusion technology and is engineered for personal care hygiene products. It is ideal for back sheets and individual wrappers of adult baby diapers, sanitary pads, and underpads. It offers an optimal balance of softness, stiffness, toughness, and excellent liquid repellency.
Textile Backsheet, also known as laminated film, is produced by laminating a polyethylene film onto a nonwoven using hot melt adhesive. It is widely used in baby diapers and adult incontinence diapers. It features a soft, textile-like texture while effectively preventing liquid penetration. Using breathable film can further enhance user comfort.
Apertured Film, also known as perforated film, is made from polyethylene. The molten resin is extruded through a die to form a film, which is then perforated. It facilitates rapid absorption and allows fluid to pass freely into the absorbent core. It is primarily used as top sheet and acquisition distribution layer (ADL) of sanitary napkins and pantyliner.
Biodegradable Film is a compostable, biodegradable, sustainable material. It is primarily used as a backsheet and for individual wrappers of adult baby diapers, sanitary pads and underpads.

Manufacturing Process
The journey from resin to final product in PE film and textile backsheet manufacturing is a complex process that requires meticulous attention to detail in every link of the chain.
Raw Material Preparation
- Polyethylene resin selection, mixture PE materials.
- Additives mixing, incorporate additives like anti-static agents, slip agents, toughening agents, or masterbatches for color or functional enhancements.
Extrusion Process
PE films are primarily manufactured using two methods:
- Blown film extrusion: polyethylene resin is melted and extruded through a multi-screw extruder. The molten material passes through an annular die, where air inflates it into a bubble. The bubble is then stretched, cooled, and wound into rolls. It is ideal for producing high-strength, multi-functional films.
- Cast film extrusion: the molten material is extruded through a flat die to form a thin film, and then cooled on a chill roll, and stretched to achieve the desired breathability. It is ideal for breathable, non-breathable, and laminated films.
- Breathability enhancement, inorganic fillers (e.g., calcium carbonate) are mixed with PE for compounding, followed by mechanical or thermal stretching to create micropores, imparting breathability.
- Lamination is applied to improve textile-like texture and strength properties, often used to bond with spunbond and air through nonwovens.
- Custom patterns can be printed on the film using flexographic or gravure printing techniques.
The film is scanned by cameras for quality control before being rolled onto shafts in large jumbo rolls, and subsequently slit into smaller rolls of the required width and packaged according to customer requirements.

The FAQs You Might Want To Know
These frequently asked questions mention almost answers you might want to know before buying PE film. We hope these informations could help you make a better decision.
What is polyethylene film?
Polyethylene film is a plastic film made from ethylene, a hydrocarbon which is mainly obtained from natural gas or petroleum. The polyethylene is abbreviated as PE, the main process technology is casting or blowing method. PE film can also be manufactured in breathable or non-breathable types with different color and printing. In addition, it can be different basic weight.
What is PE cast processing method?
PE cast method is one of PE film processing method. Cast film is a non tensile and non directional flat extruded film produced using a cast extrusion process, in which the polymer discontinuously pumping through a straight slot. Available in single-layer and multi-layer co-extrusion methods.
What is PE blowing processing method?
PE blowing method is one of PE film processing method, melting plastic particles by heating, then blowing them into membrane. It usually extrudes the polymer into a tubular film, blowing the tubular film to the required thickness by high-pressure air in a better melt flow state, cooling and forming into thin film.
What is performance difference with cast film and blown film?
Blowing PE film has more even glossiness and clean color, and better tensile strength, with higher whiteness.
What is PE non-breathable film?
Non breathable film is non-porous structure, without stretching process. It restricts water flow, airflow and water vapor. It can be one side or both sides corona treatment. It is mainly used in hygiene industry as back sheet film of baby diaper, adult diaper, underpads and feminine pads, pouch film of sanitary napkins.
What is PE breathable film?
Breathable film is also known as waterproof and breathable microporous membrane, which is characterized by breathability and impermeability. It is produced from breathable beads (PE and treated CaCO3 compound). The microporous membrane has countless interconnected micropores with ultrafine pores, about 0.01-10 micros, which can only pass through the vapor molecules with the particle size of about 0.4nm, while any raindrops or water droplets cannot pass through because of its particle size. In this way, the water vapor emitted by the human body can effectively diffuse outward through the pores, while the water droplets cannot penetrate inward, thus achieving the effect of waterproof and moisture permeability. It is widely used in hygiene and medical industry as the back sheet of baby diaper and pull-up diaper, and laminated with nonwoven fabric for back sheet and isolation gown.
Why is PE film breathable?
Inorganic fillers (e.g. calcium carbonate, talc), are added to the raw materials, the micropores are formed where the inorganic fillers (1-10 microns) combine with the film substrate being shaped during the stretching process. These micropores are sub-nanometer in size, hundreds of millions of micropores can be distributed over an area of 1 square centimeter, and these micropores allow the vapor to pass through, thus achieving breathable but impermeable properties.
What is PE film mostly used in?
It is used for a wide range of applications in disposable personal hygiene products and medical products, such as adult and baby diapers back sheet, sanitary napkins back sheet, underpads backsheet, pantyliner backsheet, top sheet of sanitary pads and pantyliner, small pouch film of sanitary napkins, bandage, medical fixing tape, isolation gowns.
