You could understand this 350g metallized film screw spout bag for soybean sauce from this video.

Introduce

This 350g metallized film screw spout bag for soybean sauce is the most appreciated in the consumer market , which is able to provide a strong and nice package for the products. The standing effect of the sachet makes it possible to include the product effectively at the point of sale.  This spout package is very practical for handling and can be produced with a lot of volume like 500ml 1000ml,  2000ml, 3000ml or even 4000ml or 5000ml.

Our company is a reliable manufacturer of these standing package with spout & closure system for kinds of soybean sauce. In this post, we are going to share our experience with you about this pouch.

Laminated Foil Structure

Generally, a mono layer film materials is unable to achieve the various functions required by this soybean sauce 350g. The amazing artwork print, robust package , good standing profile will have to need a reinforced 3-layer foil structure, which can be well sealed into a bottom gusseted standup bag. Here, the graphic below shows the common structure intended for this household detegrent doypack.

• BOPP18, is short for biaxially orientated polypropylene film with most common thickness 18 microns (equals to 0.72 gauge). After biaxial orientation process, BOPP film is enable with good mechanical strength, excellent printability, high clarity, and mechanical property, which enables it a fine print substrate film in flexible packaging area.
• VMPET12, means vacuum metallized polyester film with thickness 12 microns (equals to 0.48 gauge), is the most common used aluminum metallized films in flexible packaging field. It is with high barrier performance against mositure vapor and oxygen. The barrier performance will enable your coffee products well protected from the roaster warehouse to the consumer’s hand in a fine way.
• LDPE film, which is short for low density polyethylene film, will have to be modified to meet the particular requirements for the inside contents. Here, it mainly works as the inner sealing layer.

Usuaully, people name the foil structure BOPP18/VMPET12/LDPE ,so it can be well understood in business activities. This laminated foil also extend its wide application to many other liquid products, such as motor oil products,  windshield washer fluids, household cleaning chemicals etc.

The final thickness for this standup doypack should be 100microns, with tolerance +-5%. and the toughness of this foil will be enough to finalize good package profile for 350g of  soybean sauce products.

Ok, let’s get into deeper understanding on the performance of this soybean sauce package.

Soybean Sauce Metallized Film Screw Spout Package Performance

More Sustainable Options

With increasing burden on the plastic pollution, more and more products are now seeking for packages which are more sustainable, like compostable packages, recyclable mono materials packages, plant-based materials packages. They all proves to be more eco-friendly than the traditional multilayer packages which are even very difficult to be recycled.

1) Home compostable film material packages

Thanks to the fast development of plant-based film materials, now we are able to present the multi-layer standup pouch and roll foils in full home compostable options.

The compostable substrate films are as below.

1. BOPLA Film
2. PLA+PBAT Film
3. Kraft Paper
4. Metallized Paper
5. Cellulose Paper
6. Metallized Cellulose Paper
7. PBS Film

Based on the compostable substrate film, we are developing kinds of multi-functional packages for various applications, as below

1. High barrier performance packages, for roasted coffee beans, nutritions, milk powder, snacks or biscuits.
2. Alkaline resistant packages for hand wash, laundry cleaning chemicals etc
3. Frozen packages, like fish, noodles, or soup products
4. Vacuum packages for vegetables, rice, red beans etc
5. Hot filling packages for juice
6. Microwave packages

Along with the extentions of compostable film materials, more and more products are now starting to get well packed in home compostable packages, with some well-applied foil structures as below.

Biodegradable Foil Laminate	WVTR (g/m2/24hr)	OTR (cc/m2/24hr)

2) Mono Materials Recyclable Pouch Packages

Mono meterials pouch packages are truly recyclabled, as they can be easily processed into plastic granules which can be used again for other applications. However, for the traditional multilayer laminates, take PET/LDPE for example, it is difficult to be processed, as PET and LDPE are quite different material, and can not be melted under the same conditions. That’s why momo materials pouch packages are becoming so widely popular in the packaging field, and highly reputed in the consumer market.

At present, mono materials pouch are basically divided into Polyethylene channel and Polypropylene channel, with polyethylene channel much more popular, as they can be converted into kinds of standup pouch packages with relative high performance.

Here we list the film materials that can be well intended for mono-materials recyclable pouch packages.

1. MDOPE Film
2. BOPE Film
3. APE Film
4. LDPE Film
5. LLDPE Film
6. CPE Film
7. ABOPP Film
8. CPP Film
9. VMCPP Film
10. VMBOPP Film

Various foil laminates can be achieved based on above film materials with different properties, which is intended to meet the particular requirements for specific product. Some foil laminates are well-known as below.

1. MDOPE/APE
2. MDOPE/LDPE
3. MDOPE/EVOH-LDPE
4. MDOPE/HDPE/APE
5. MDOPE/BOPE/APE
6. BOPE/APE

Upon our experience, mono materials pouch can be well intended for milk powder  products.
