Product Details

Regenerated cellulose film is a degradable material made from natural cellulose such as wood pulp and cotton pulp. t goes through a seriesof chemical changes such as alkaization, xanthation and casting and change into another regenerated cellulose film. Compared with paperregenerated cellulose film not only has better flexibility, but also has the same transparency as glass.

Regenerated cellulose film has the advantages of non-toxic and tasteless, high-temperature resistance, anti-static, and direct contact withfood, making it widely used in fields such as food, medicine, labeling, tape, cosmetics, precision instruments, etc.

In recent vears, the global polution problem has become increasingly severe, in order to control the continuous deterioration ofthe environment, a series of environmental protection policies and requlalions have been introduced at home and abroad.

With the deepening of policiesenvironmenlal polution has become an undeniable issue and has become the focus of alobal altention foday, As a nalural and environmentallfriendly material, regenerated cellulose film can quickly degrade in soi without causing secondary pollution to the environment, it is a natural'fertilizer" that alians with today's human vision for a better living environment.With the increasing globalization of"plastic restricion", regenerated cellulose films will become the backbone of buiding a "green home" in the future.

Semi-barrier regenerated cellulose film is a high-performance and sustainable transparent packaging film, made from natural wood pulp through advanced technology. It perfectly combines the outstanding optical performance, excellent mechanical strength and natural biodegradability of traditional regenerated cellulose membranes (such as cellophen), and significantly enhances its barrier performance against oxygen, aroma and oil for specific application requirements, reaching a "semi-barrier" level. This film represents the ideal balance between eco-friendly packaging and functional requirements.

Biodegradable Cellulose Film Core Advantages Characteristics:

• Outstanding semi-barrier performance:

Oxygen barrier (OTR) : Significantly superior to standard regenerated cellulose membranes, it can effectively slow down the oxidation and deterioration of the contents, and extend the shelf life and flavor stability of foods (such as dried goods, nuts, baked goods, some candies, and cheeses).

Aroma barrier: It can effectively lock in the inherent aroma of the product and prevent the invasion of external odors, maintaining the pure flavor of the product.

Oil barrier: It offers excellent oil-proof performance and is suitable for foods with moderate oil content (such as biscuits and fried snacks) as well as some cosmetics and personal care products, preventing oil stains from seeping out and contaminating the packaging.

• Environmental protection advantages derived from nature:

Renewable raw materials: The main raw material is sustainably managed forest wood pulp, which is a renewable resource.

Biodegradable & compostable: It can be completely biodegraded under industrial composting and household composting conditions, eventually converting into water, carbon dioxide and biomass, significantly reducing plastic pollution and landfill burden.

Non-plasticized: Free of plastic micro-particles, it avoids long-term harm to the environment.

Transparency & High Gloss: With crystal-like transparency and high gloss, it perfectly showcases the product's appearance and enhances the shelf's appeal.

• Excellent physical properties:

High strength and toughness: It has excellent tensile strength and tear resistance (especially in a wet state), ensuring reliability during processing and transportation.

Dimensional stability: Maintain stable dimensions under normal temperature and humidity conditions to reduce the risk of packaging deformation.

Heat sealing property (usually requiring coating) : It can be combined with suitable coatings (such as nitrocellulost, PVDC, acrylic or bio-based coatings) to achieve reliable heat sealing and meet the requirements of automated packaging. The selection of coatings has also further optimized its barrier performance.

Good printability: The surface is easy to be printed in high quality, presenting bright colors and clear patterns.

• Good air permeability (MVTR) :

Maintaining the relatively high water vapor transmission rate inherent in regenerated cellulose membranes (compared to high-barrier plastic membranes) is beneficial for products that require "breathing" to prevent condensation or maintain specific humidity, such as fresh produce and some baked goods. This is also one of the reasons why it is defined as "semi-barrier" rather than "high-barrier".

Biodegradable Cellulose Film Application Scenarios

It can be applied to single-layer direct packaging, or the overall wrapping or sealing packaging of objects after compounding. For example,31-35g/n can be used for cigarette packs, non-load-bearing dry gift bags, accessory packaging, etc., and can also be used for food packaging bags or the inner layer oxygen barrier layer of multi-layer composite materials. 45-60g/㎡ can be used for cigar packaging, food baking bag making, snack, candy, grain food packaging, clothing, labels (white opaque label film can be customized), and envelope Windows, etc.

Biodegradable Cellulose Film Specification parameters (example, specific details need to be confirmed according to the product model) :

Thickness range: typically 28-45 micrometers (μm) or 1.1-1.8 mil

Oxygen transmission rate (OTR) : Approximately within the range of 10-100 cc/m²/day/atm (23°C, 0%RH), significantly lower than that of standard regenerated cellulose membranes (typically > 1000), but higher than that of high-barrier materials such as EVOH (< 1).

Water vapor transmission rate (MVTR) : approximately 300-1000 g/m²/day (38°C, 90%RH), which is higher than that of high-barrier plastic films.

Tensile strength (MD/TD) : High, with specific values depending on thickness and grade.

Elongation at break (MD/TD) : Moderate.

Glossiness: Extremely high (> 80%).

Haze: Very low (< 2%).

Application

Food packaging

• Dry goods (rice, flour, beans, tea, coffee)
• Nuts, seeds, cereal bars
• Baked goods (biscuits, cookies, some pastries)
• Candies, chocolates (preventing oil leakage and protecting aroma)
• Cheese slices/pieces
• Some snacks (potato chips, popcorn - need to be combined with appropriate coatings)
• Fresh produce (fruits and vegetables that need to breathe - taking advantage of their breathability)

Non-food packaging

• Cosmetics and skin care products (soap bars, bath salts, facial mask powder)
• Medicines and health products (blister packaging, outer packaging, small bags)
• Gift packaging
• High-end clothing and textile packaging (transparent window bags)
• Labels and sleeve labels

Usage Tips:

The specific barrier properties (oxygen, water vapor, aroma, oil) may vary depending on the base film formula, coating type and thickness. When making a selection, it is necessary to match the specific application requirements.

Its excellent oxygen barrier property is optimal under dry conditions. A high humidity environment may have a certain impact on its oxygen barrier property (but it is usually still better than standard regenerated cellulose membranes).

Applications that require heat sealing must select models with appropriate heat sealing coatings.
