The Widespread Application of PA/PE Film in Thermosealing Packaging Abstract: This article comprehensively explores the extensive use of PA/PE film in various thermosealing packaging applications, including food blister boxes, fruit boxes,
2.2 Mechanical Strength
PA/PE film exhibits high mechanical strength, which makes it durable and resistant to punctures, tears, and abrasions. In food packaging, this property is vital for protecting the contents during handling, transportation, and storage. For instance, in the packaging of sharp-edged food items like cutlery or products with irregular shapes, the film's strength prevents it from being damaged and ensures the integrity of the package. In the pharmaceutical industry, this film helps in protecting tablets or capsules from any external force with its mechanical strength in the highest regard for their safety and integrity. 2.3 Heat Sealability The heat sealability is one of the major features characterizing this film and its applications related to thermosealing packaging. This kind of film can be sealed easily by heat to a strong and reliable bond. It also makes for efficient and effective packaging. The heat-sealing characteristics of PA/PE film allow the production of airtight and tamper-evident seals in the manufacture of food blister boxes, fruit boxes, and cutlery boxes. The sealant characteristics allow for an effective sealing process where the sealing is appropriately done to an airtight package to prevent leakages and other forms of contaminations. In the case of beverage cups, the film can be heat-sealed to form a secure lid, keeping the drink inside and maintaining its quality.

PA/PE film is quite transparent, which makes it easier for consumers to view the content of the package. This is quite beneficial in food packaging because it enhances the appearance of the product and helps consumers make better choices. For example, in fruit boxes, the transparency of the film showcases the freshness and quality of the fruits inside. The film's surface is also receptive to printing, enabling manufacturers to print attractive labels, nutritional information, branding elements, and product details directly onto the package. High-quality printing not only provides essential information to the consumers but also adds to the overall aesthetic value of the product, making it stand out on the shelves.
2.5 Chemical Resistance
The film is chemically resistant to a wide range of substances, which is important in both food and pharmaceutical packaging. It does not react with the food or drug products, ensuring the safety and integrity of the packaged items. In food packaging, it can withstand contact with various food acids, oils, and spices without degrading or leaching harmful substances. In pharmaceutical packaging, it is compatible with different drug formulations and does not affect the potency or stability of the medications.

3.1 Food Blister Boxes
PA/PE film is widely used in the production of food blister boxes. The process begins with the thermoforming of the film. It is heated to the extent that it becomes pliable and molded into the shape of the blister cavity by vacuum or pressure-forming techniques.

3.3 Cutlery Boxes
For the packaging of cutlery, PA/PE film is one of the best solutions. The high mechanical strength of the film prevents the sharp edges from the cutlery items from puncturing through the packing and creating hazards.

FOOD BOX COVER FILM 3.4 Beverage Cups
PA/PE film is used in the production of lids for beverage cups. The film is heat-sealed onto the cup rim, forming a tight seal that prevents any leakage of the beverage. The barrier properties of the film help to maintain the carbonation and flavor of carbonated drinks and prevent the absorption of odors from the surrounding environment for other beverages. The transparency of the film allows consumers to see the contents of the cup,

4.1 Pharmaceutical Seals
In the pharmaceutical industry, PA/PE film is used for sealing various types of pharmaceutical packaging, such as blister packs and bottles. The excellent barrier properties of this film protect the drugs from moisture, oxygen, and those environmental conditions that can contribute to degradation of their quality and potency.

5.1 Coextrusion Process
Manufacturing of PA/PE film involves a coextrusion process normally. In this process, the PA and PE resins are melted separately and then combined in a coextrusion die. The die is designed to form a multilayer structure whereby the PA layer and the PE layer are extruded together in one film. Depending on the specific requirements of the packaging application, different thicknesses and ratios of the PA and PE layers can be produced. The coextrusion process requires precise control of temperature, pressure, and flow rate to ensure the uniformity and quality of the film. The addition of additives, such as antioxidants, slip agents, and antiblocking agents into the resins before extrusion can improve the film's performance or processing characteristics.5.2 ORIENTATION AND ANNEALINGAfter the coextrusion of the film,

it can be subjected to an orientation that enhances the mechanical properties. This can be done in machine direction, transverse direction, or biaxial direction through the stretching operation which aligns the polymer chains, making the film strong with enhanced stiffness.

To improve the printability and heat sealability of the film, surface treatment may be carried out. One common method is corona treatment, which uses a high-voltage electrical discharge to modify the surface energy of the film. This makes the surface of the film more receptive to inks and adhesives, thus giving improved printing and sealing results. Another method is plasma treatment, which can also enhance the surface properties of the film by creating reactive species on the surface. These surface treatments are of great importance for ensuring the proper adhesion of printed labels and the formation of strong heat seals in the packaging process.
