INTRODUCTION
Cellulose nanofibers (CNF) offer an interesting environmentally friendly material for food packaging due to its abundance, biodegradability and renewability. Nowadays, there is a great interest in food packaging with specific characteristics such as water vapor barrier and antimicrobial properties, in order to preserve the quality and safety of food, as well as to extend the shelf life of food.
MATERIALS AND METHODS 1 Materials
- CNF Preparation
- Films preparation
- Analysis a. Transparency
- Culture media preparation a. Media of Bacillus subtilis
The water vapor permeability of the films was measured by the weight loss of water vapor through the film. The film samples (round shape with 1 diameter) were placed in the center of the media.
RESULTS AND DISCUSSION
- Transparency
- Mechanical properties
- Hydrophobicity
- Water Vapor permeability
- Anti-microbial property
The surface of cellulose nanocomposite films becomes low hydrophobic when the amount of nanoclay is added. The increasing amount of nanoclay in the cellulose nanofiber films showed a significant improvement in the water vapor barrier properties and surface hydrophobicity of the films, while the tensile properties and transparency of the films were least sacrificed.

Characteristics of some agave accessions fibers for pulp and papermaking
The use of agave fibers for pulp was preferred over the use of agave leaves due to the bulkiness of agave leaves. As long fibers, the tear index of agave accessions was consistent with the Indonesian standard for NBKP, and the burst index and tensile index were not appropriate for needle bleached kraft pulp and did not meet the bleached leaf kraft pulp.

Appropriate scale of environmentally friendly art paper production from abaca and banana leaves and its potential as
This is because the length of the fibers and the quality of the abaca fibers are better than those of dried banana leaf. This happens because the intensity of production of art paper mills on a scale of TTG (suitable methods) is quite short (about 10 minutes). Based on the results of the liquid waste boiling test process conducted at the Laboratory of Chemistry and Agro Provincial Agriculture Cikole Lembang, West Java in Bandung, liquid waste is potential for NPK fertilizer.

A review: non-wood plant fiber for biocomposite
The length of the fiber in the manufacture of composite fibers using polymer matrix affects the strength and modulus of composites. The greater the fiber length to diameter (aspect ratio), the greater the strength of the composite. From the test results, it is known that the quality of the bamboo fiber composite of bamboo strips cooked by soda process is better than the composite bamboo pulp.

The results of the analysis of variance showed that the proportion of raw materials, concentration of PVAc adhesive, as well as the interaction of the two factors used (proportion of raw materials and concentration of PVAc adhesive) had a significant effect on tensile strength and resistance to tear in 5. %. Data on the influence of raw material proportion on tear resistance can be seen in Table 4. The higher proportion of nypa palm leaf pulp resulted in a decrease in the mean value of tensile strength and tear resistance.
Non-wood pulping in the Philippines – a background and its outlook under the paper industry roadmap
Founded in 1975 in the province of Bulacan, initially to meet the demands of cement manufacturers for kraft paper for bags, the Phinma Group was the country's largest non-wood pulp and paper company. PROSPECTS FOR NON-WOOD FIBERS IN PAPER INDUSTRY PLAN In an industry plan submitted to the State Board of Investment, the Philippine Paper Manufacturers Association of the Philippines (PPMAI) identified the reasons why the pulp and paper industry in the Philippines has not developed as well. strongly than with our Asian neighbors;. Cultivation of kenaf has been attempted in the country, but the results have not been promising, so its potential for pulp and paper has not been exploited until now.

Potency, stock and prospect of oil palm biomass for pulping and papermaking business opportunity
Biomass from Palm Oil Industry – Its Availability and Current Uses
- Oil Palm Trunk
- Oil Palm Fronds
- Empty Fruit Bunch
- Oil Palm Fruit Fiber and Oil Palm Shell
Solid biomass from an oil palm plantation includes oil palm trunk (OPT) from replanting when the palm has reached 25 to 30 years of age; and oil palm leaves (OPF) from pruning and replanting activities. In line with the growing concern about the environmental issue, the palm oil industry must be managed in a balance between production (CPO and PKO) and the environment. Therefore, two types of oil palm biomass (EFB & POME) can be saved using integrated composting technology.
Stock of Oil Palm Biomass Based on Current Applied Technologies
- Oil palm trunk
- Fronds
- Empty fruit bunch
- Shell
Thus, the amount of oil palm trunk that can still be used for pulp production is approximately 10 million m3 per year. Leaves are one of the vast biomasses of oil palm available in plantations due to pruning activities.
