Nylon is a synthetic polyamide polymer. Also known as BOPA. BOPA is known for its exceptional strength, durability, and barrier properties, making it suitable for a wide range of applications, including food packaging, pharmaceuticals, electronics, textiles, and industrial packaging.
They are commonly used for flexible packaging, vacuum pouches, shrink sleeves, laminations, and other specialized applications where strength, barrier properties, and durability are essential. Nylon's resilience plays a crucial role in preventing breakage, particularly in products prone to impact.

NIAITE offers various Nylon film types to meet different packaging requirements.
Nylon film, renowned for its exceptional properties, stands as a versatile material in the realm of packaging.
Nylon films are highly flexible and durable, providing flexible packaging with elevated strength and resistance to breakage. Commonly utilized in structures like NY/PE and PET/NY/PE, it finds its place in diverse packaging solutions, ranging from vacuum packaging to heavy-duty applications.
They are eco-friendly and recyclable, avoiding the generation of harmful chemical pollutants in the environment.
Nylon films are a relatively inexpensive synthetic material, making them an economical choice for packaging applications.
Nylon films are impermeable, making them ideal for food packaging as they prevent the entry of air, preventing packaging expansion.
Nylon films are easily recyclable and compatible with microwave usage, providing convenience for consumers.
Nylon films are extensively used in food packaging due to their versatility, and applicability to various materials.
Using nylon in packaging increases peel strength, preventing delamination and ensuring package integrity.
Aluminized nylon (TNY) enhances film barrier properties, making it suitable for high-barrier product bags.
BOPA films also have certain disadvantages that need to be considered in packaging applications.
Nylon film is highly prone to absorbing moisture and alcohol, with a saturation level reaching 8–9%. This can affect dimensional stability and reduce the mechanical performance of the film. Once nylon film absorbs moisture, it changes, becoming soft, wrinkled, and deformed.
Recommendation: It is recommended to dry the nylon film in a curing room at 45–50°C for 1–2 hours before use. The moisture content of the film should not be overlooked. Before production, check the film's moisture content; if it exceeds 3%, it should be carefully dried before use.
The bow effect is a unique defect of nylon film. It occurs in both synchronous and step-by-step production processes, although the bowing degree may vary. The larger the bow angle, the greater the balance shrinkage rate, with a rate of 1.5% indicating minimal shrinkage and fewer premium-grade products.
Monitoring the workshop's humidity and dew point is crucial. Any condensation should be wiped off promptly. Typically, the production environment should maintain a temperature of 23°C ± 3°C and a humidity level of 60% ± 5%. If the humidity exceeds 75% RH, pausing or stopping composite production is recommended.
BOPA film has poor light resistance. In high-temperature environments, it reacts with oxygen in the air, turning yellow-brown and eventually breaking down. It is also not resistant to strong acids and oxidizers, and therefore cannot be used as acid-resistant material.
The versatility of nylon films makes them widely applicable to various flexible packaging, including both food and non-food packaging.
When our products require protection against impact and breakage, Nylon (NY) is a preferred choice. Its toughness plays a crucial role in preventing package breakage when products are dropped, making it a common structural choice for household products like laundry detergent, that is NY/PE.
For conventional food packaging, such as snacks, PET/NY/PE structures are typically selected, providing excellent barrier and mechanical properties.
For retort products and sauces that require high-demand packaging, Nylon is often used to enhance packaging toughness and product protection. PET/AL/NY/RCPP is a commonly utilized material structure.
For products with a critical need for impact resistance, especially in heavy-duty packaging, double-layered Nylon protection (NY/NY/PE) becomes essential.
In the case of Bag-in-Box (BIB) packaging, the inclusion of NY in NY/PE&PE structures also provides crucial impact resistance.
Vacuum packaging also often selects nylon (NY) materials. NY/PE and PET/NY/PE are commonly used structures.
When high barrier properties are required, aluminum (AL) is a preferred choice, but due to cost considerations, Alox-Nylon becomes an excellent alternative.
Nylon can be selected for almost any flexible packaging structure except single material ones.
