Noodle packing: What material is strong and moisture-proof?

As a traditional noodle in our country, noodles have a very large consumer market, and the demand for noodles is increasing day by day. In order to facilitate consumers to buy and eat noodles, manufacturers usually choose to pack noodles in packaging bags. So, what material should be chosen for the hanging bag? Let's talk about it.

First of all, we need to understand the characteristics of noodles and packaging requirements. Hanging noodles are dry noodles, which are easy to store, easy to carry and taste good. Therefore, for hanging bags, the following requirements need to be met:

Robustness: Wall packaging needs to be strong enough to withstand pressure and collisions during transportation, handling and storage. Strong packaging protects the wall from damage and maintains the integrity and quality of the product.

Moisture-proof: Hanging noodles are a kind of food that is susceptible to moisture, so the packaging needs to have good moisture-proof performance and can effectively block the intrusion of external moisture. Moisture-proof packaging can keep the noodles dry and extend the shelf life of the product.

Sealing: The hanging package needs to have good sealing performance, which can effectively prevent the leakage and pollution of the hanging surface. Good sealing can maintain the freshness and taste of the noodles, providing a good eating experience.

Easy to open: the hanging package needs to have an easy to open design, convenient for consumers to open the package. The open part can be zipped, pulled or easily torn to provide a convenient access experience.

Easy to store and carry: Hanging packaging needs to be easy to store and carry, easy for consumers to buy and use. The right size and packaging form can be easily placed in cabinets, shelves or carried out.

Good printing effect: Hanging packaging usually requires the printing of brand identity, product information and patterns to attract consumers on the packaging. Good printing effect can enhance the product's brand image and market competitiveness.

According to the above requirements, there are three common hanging bag materials: OPP/CPP, PET/PE and PET/VMPET.

OPP/CPP

OPP/CPP is one of the most common hanging bag materials on the market, with the advantages of moisture, sealing, high temperature and pressure resistance. In addition, OPP/CPP also has the advantages of low cost, good printing effect, and good environmental performance. Therefore, most noodle manufacturers will choose this material as a hanging bag.

PET/VMPET

PET/VMPET is a composite material, in which PET has the advantages of high temperature resistance, oil resistance and high transparency, while VMPET has the advantages of high barrier, moisture, water and corrosion protection. Therefore, PET/VMPET material packaging bags are also suitable for hanging packaging, which can better protect the quality of hanging noodles and extend the shelf life.

PET/PE

The composite method of polyester (PET) and polyethylene (PE) can provide better moisture resistance and robustness. PET as the outer layer, has good wear resistance and tear resistance, can effectively protect the bag from physical damage. As the inner layer, PE has good moisture resistance and can block the intrusion of external moisture.

BOPP/PE

The combination of biaxial polypropylene (BOPP) and polyethylene (PE) provides excellent moisture resistance and robustness. BOPP, as the outer layer, has good transparency and wear resistance, which can show the appearance and quality of the product. As the inner layer, PE has good moisture resistance and can keep the dry state of the hanging surface.

PET/AL/PE

The combination of polyester (PET), aluminum foil layer and polyethylene (PE) provides excellent moisture resistance and oxidation resistance. PET as the outer layer, has good wear resistance and tear resistance. As the middle layer, the aluminum foil layer has good moisture resistance and heat insulation, which can effectively block the intrusion of external moisture and oxygen. PE acts as the inner layer to provide additional moisture protection.

PA/PE

The combination of nylon (PA) and polyethylene (PE) can provide better moisture resistance and robustness. As the outer layer, PA has good wear resistance and tear resistance, which can protect the lined bag from physical damage. PE, as the inner layer, has good moisture resistance.

The above composite methods are some commonly used options for hanging bags, and the specific selection should be carried out according to the requirements of the product and the budget. At the same time, reasonable packaging design and manufacturing process is also very important to provide better robustness, moisture resistance and packaging appearance.
