Key Steps and Testing of Protective Films

The experiment covered each processing stage, from applying a protective film to the final product to using standard and modified PE films to test film compatibility with different surfaces.

1. Film Application: PE protective films were applied to each panel surface. Shallow texture panels like melamine high gloss, UV high gloss, UV matte, PVC shallow texture, and PET showed strong compatibility with over 90% pass rates for standard and 100% for modified films. Deep textures like melamine and PVC initially showed poor performance with standard films (0% pass rate) but improved with modified PE films, with pass rates of 100% for melamine deep texture and 40% for PVC deep texture.
2. Cutting: Panels were cut into specified sizes. Shallow texture panels maintained a 100% pass rate with both film types, while melamine deep texture achieved 95% with modified film, PVC deep texture 86% with modified film, and 64% with standard film.
3. Edge Banding: Each panel received a PVC edge band. Shallow-texture panels performed well, with a 100% pass rate, while melamine deep texture achieved 92% and PVC deep texture reached 81%.
4. Drilling: Drilling tests showed that shallow texture panels remained at a 100% pass rate. Melamine deep texture had a 92% pass rate, while PVC deep texture reached 71%.
5. Grooving: U-shaped grooves were milled along the thickness of the panels. Shallow texture panels again achieved a 100% pass rate, melamine deep texture 92%, and PVC deep texture 64%.

Test Results and Protective Film Suitability

Performance across different tests is summarized as follows:

• Shallow Texture Panels: Panels with melamine high gloss, UV high gloss, UV matte, PVC shallow texture, and PET finishes achieved consistently high performance with both standard and modified PE films, with no issues of peeling or film damage throughout processing.
• Deep Texture Panels: For melamine deep texture panels, modified PE film provided excellent protection with 100% pass rates in application and cutting and approximately 92% in edge banding, drilling, and grooving. PVC deep texture saw improvement with modified PE film in the application stage, reaching a 40% pass rate and improved pass rates in cutting (86%), edge banding (81%), drilling (71%), and grooving (64%).

Conclusions and Recommendations

The results suggest that shallow texture panels are well-suited for standard PE films, especially with a recommended thickness of 50-60 μm and peel strength between 28-96 N/m. This combination can preserve surface quality while preventing adhesive residue. For melamine deep texture panels, a high-strength, flexible modified PE film is recommended for best results. The tested films didn’t fully meet protection requirements for PVC deep texture panels, indicating the need for further research to find an ideal protective film solution.

PET and PE protective films have different properties, characteristics, and uses.

1. Material: PET protective film is made from polyester resin, while PE protective film is made from polyethylene resin.

2. Physical properties: PET protective film is highly transparent, complex, and abrasion-resistant. It is also resistant to scratching and chemical attacks. PE protective film is relatively soft and has lower hardness and transparency but is more flexible and impact-resistant.

3. Fields of application: Due to its high hardness and abrasion resistance, PET protective film is often used in applications that require high protection, such as electronic products, mobile phone screens, tablet computers, monitors, etc. PE protective film has better flexibility and impact resistance and is often used in applications that require flexible adhesion, such as furniture, flooring, and car interiors.

4. Processing characteristics: PET protective film is relatively complex and must be fixed using heat pressing or gluing methods. On the other hand, PE protective film can be directly attached to the surface of an object because of its good flexibility.

In summary, PET and PE protective films differ in material properties, physical characteristics, usage, and processing methods. The choice of protective film to use depends on the specific application requirements and the required performance characteristics.

Polyethylene (PE), one of the five major synthetic resins, plays a significant role in today’s global market. China is now the world’s largest importer and the second-largest consumer of PE. The material is categorized into three primary types: High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Linear Low-Density Polyethylene (LLDPE).

Comparing HDPE, LDPE, and LLDPE

1. High-Density Polyethylene (HDPE)

HDPE is a nontoxic, odorless material with a 0.940 to 0.976 g/cm³ density. It is produced under low pressure using Ziegler catalysts, also called low-pressure polyethylene.

Advantages:
HDPE is highly crystalline, nonpolar, and resistant to most household and industrial chemicals. It offers excellent moisture and vapor barriers and is well-suited for water resistance applications.

Disadvantages:
However, HDPE’s aging and environmental stress crack resistance isn’t as strong as LDPE. To counteract this, additives like antioxidants and UV absorbers are included to improve durability.

2. Low-Density Polyethylene (LDPE)

LDPE is a lightweight material with a density between 0.910 and 0.940 g/cm³. It’s produced under high pressure (100–300 MPa) and is commonly called high-pressure polyethylene.

Advantages:
LDPE offers excellent flexibility, transparency, and low-temperature performance. It also provides good chemical resistance to acids, bases, and salts. Furthermore, LDPE has excellent electrical insulation properties and low moisture absorption.

Disadvantages:
LDPE’s mechanical strength, moisture, and gas barrier properties are inferior to HDPE’s. It also has a lower melting point, making it less suitable for high-temperature applications.

3. Linear Low-Density Polyethylene (LLDPE)

LLDPE has a density range of 0.915 to 0.935 g/cm³ and is produced by copolymerizing ethylene with small amounts of higher alpha-olefins. Its linear molecular structure contains fewer branches than LDPE.

Advantages:
LLDPE combines the strengths of HDPE and LDPE, offering excellent tensile strength, toughness, and flexibility. It resists environmental stress cracking and can withstand acids and organic solvents.

Disadvantages:
Compared to LDPE, LLDPE can be slightly less transparent but is more robust and more durable, making it ideal for demanding applications.

Distinguishing Between LDPE, LLDPE, and HDPE

• LDPE: Feels soft, white translucent, burns with a yellow flame, and has a waxy smell.
• LLDPE: Swells when exposed to benzene over time; becomes brittle in prolonged contact with hydrochloric acid.
• HDPE: Requires a higher processing temperature, around 180°C, and has a higher density than LDPE.

Conclusion

All three materials—HDPE, LDPE, and LLDPE—play critical roles in various applications. Their nontoxic, odorless properties and exceptional insulation and moisture resistance make them widely used in agriculture, aquaculture, reservoirs, and artificial lakes. HDPE stands out for its superior chemical resistance, while LDPE is known for its flexibility and low-temperature performance.

The whole production process of polyethylene protective film.

The protective film’s production process is intended to be of high quality. PE protective film molding methods are many. Three of the more common are casting, extrusion, and blow molding. The production process breakdown can be divided into blown film, coating, printing, inspection, rewinding, slitting, and packaging. The processes in each process are different, and each method is not indispensable.

Blown Film.

Blown film is plastic that is melted in the extruder and extruded through the ring, which dies into a film tube. Compressed air blows, cools, and shapes the film.

Coating.

The adhesive is prepared according to the polyethylene protective film’s specifications, model, and applicable products. Then, a coating machine evenly coats the adhesive on the substrate.

Printing.

In a gravure printing press, the printing plate is immersed in an ink cartridge, the ink is removed from the non-engraved portion of the plate with a squeegee, and the ink is transferred to the printed substrate under an embossing rubber roller.

Testing.

A quality inspector will conduct product quality inspections during the production process of PE protective film, such as batching, film blowing, printing, coating, etc.

Rewinding: Semi-finished products are rewound on the inspection machine.

Semi-finished products are rewound on the inspection machine. Suppose the shape, size, and color error between the pattern fed back by the sensor and the standard sample inputted into the computer is out of a particular range. In that case, the inspection machine will automatically stop the inspection. The inspection process reduces post-processing spreading and improves product quality.

Slitting.

The slitting process divides large-size rolls of film into desired sizes. With the increasing use of automated packaging equipment, more and more rolls of film are being delivered from the factory.

Packaging.

The inspected and cut PE film products are transported to the packaging machine for packaging.
