Cleaning chemicals are one of the most commonly used products in our homes, so the appearance of the products is also rich and varied. The most commonly used are bottled and packaged. Compared with bottles, bags save more space and are cheaper. And they can be printed with beautiful designs and brand logos. Moreover, they can meet the needs of most consumers.
The stand-up pouch makes a better show when it stands on the goods shelves and has a folded gusset at the bottom to keep more products. In order to guarantee that the items are adequately safeguarded during the filling, transportation, and distribution processes, it would be necessary for the materials to be tough and permanent.
To reach the antioxidant effect and store the antioxidants effectively, generally speaking, the film material of the spout pouch for the natural antioxidants is PET/BOPA/LDPE.
For this kind of large-capacity product, and to have a good standing effect, PA is a good choice. It will make the packaging more rigid and the standing effect more beautiful. Furthermore, the creative artwork design can be printed on all sides of the standup pouch, including all the information for branding and sale, which makes the final package more attractive to consumers.
As a well-known flexible converter located in Qingdao, China, we are making the best use of the packaging film materials in the market, listed below.
- fossil chemical polymer films
- Aluminum foil metal sheet
- vacuum metalized film materials
- Ceramic film substrates
- plant-based biopolymer materials
- biodegradable film materials
- compostable substrate films
- Fully recyclable substrate films
We are devoted to creating story-telling standup screw cap bags for cleaning chemicals that increase product sales and establish a good brand image.

In this post, we will analyze the exact foil materials of this 30000ml cleaning chemicals standup bag, hoping it could serve as a reference for your products.
Ok, let’s get into the details of this standup screw cap spout bag.
Packaging Foil Materials

This foil material has a reinforced structure with excellent properties for spicy chili sauce packages. The foil structure is PET/BOPA/LDPE, and the graphic is as below.
It is made of triplex layers, with the outside PET film of 12 microns working as the print substrate film, the BOPA film of 15 microns working as the middle supportive and barrier layer, and finally, the LDPE film working as the inner sealing layer. The thickness of the LDPE film should be adjusted to suit the requirements of 3000ml cleaning chemicals.
Next, let’s get a deeper understanding of each substrate film material.
PET12 Film

PET film, or polyethylene terephthalate film, is a thermoplastic polymer resin that is a type of plastic film. It is a versatile material with many uses due to its physical, mechanical, optical, thermal, electrical, and chemical properties. PET film is available in various thicknesses, widths, and transparencies.
BOPA
BOPA stands for Biaxially Oriented Polyamide, which is also known as biaxially oriented nylon (short as NY) film. It’s a versatile and flexible material that’s made by biaxially stretching polyamide resins using a flat cast die process, the three-layer co-extrusion method, and the two-step tenter frame orientation.

BOPA film is especially popular for food packaging because it can help keep food fresh and can display important information such as whether the product is organic, vegetarian, or halal, and if it contains allergens. The growing demand for packaged food and the pharmaceutical industry is expected to drive the growth of the BOPA film market in the coming years.
LDPE Film
LDPE film is short for low-density polyethylene film, which is the most used inner sealing layer for standing spicy chili sauce bags. LDPE is also lightweight, easy to fabricate, and has good chemical and impact resistance. LDPE is recyclable and reusable, making it a popular alternative to traditional plastic. LDPE is nontoxic, non-contaminating, and has a high degree of break resistance. Most importantly, LDPE membrane can be modified against the requirement of specific products, and finalize the package with great seal strength and protection. The thickness of the LDPE membrane film will be decided against the particular application.

The property of the LDPE film should be modified to resist the alkaline corrosion of the liquid detergent. Different formulas of detergent liquids may require a particular modification of the low-density polyethylene film. If you need further assistance, you can reach out to us.
The customer artwork is printed reversely on the inner side of the first PET film layer in the gravure printing system. These 3 layers are bonded together into a finished laminated foil material under the dry lamination or solvent-free lamination process. Usually, we describe the finished laminate as PET/BOPA/LDPE foil.
Barrier Performance
Usually, the barrier performance of a multi-material laminate is evaluated by WVTR (short for water vapor transmission rate) and OTR (Oxygen Transmission Rate). The below table shows the typical value of the WVTR and OTR of the most common substrate films in flexible packaging.

Upon experience, the partial packages for spicy chili sauce should be light-shielding to protect the formula work as expected. The main reason is to prevent light from accelerating its oxidation process, causing oil deterioration and loss of flavor. Therefore, it is necessary to ensure that the storage environment of the chili sauce is dark and away from light, can effectively extend its shelf life and maintain its flavor.
Furthermore, the chili sauce product will be kept from oxygen and moisture, to stay fresh as long as possible. However, please keep in mind that, the barrier property of this laminated foil is just a part of the measures taken to ensure the shelf life of chili sauce products.
You can easily find out the typical values of moisture vapor transmission rate and oxygen transmission rate of this multilayer foil PET12/BOPA15/LDPE.
Item | Standard | Unit | Typical Value |
Water Vapor Transimission Rate | ASTM E 96 | g/m2/24hr | 19.5 |
Oxygen Transmission Rate | ASTM D 372-99 | cc/m2/24hr | 8.5 |
So, some reinforced foil structures are better protections for the freshness and flavors, with some available items listed below.
- PA/VMPET/LDPE
- BOPP/BOPA/LDPE

More Sustainable Materials Options
Along with the increasing burden of fossil-chemical polymer materials discarded into our environment, there is an unprecedented demand for sustainable packages which leads to a more eco-friendly activity of the business. Upon the recent investigation of the juice market, more and more consumers are more likely to purchase a product that acts toward environmental sustainability.
Compostable Packaging Materials

The compostable packages are based on plant-based fibers like cellulose, or bio-mass like corn starch, cassava, or sugarcane. The resins derived from these resources are usually named bio-polymer, which can break down into inorganic elements under the functions of algae, bacteria, and other microorganisms.
At present, we have developed several compostable foil materials that can be intended for chilli sauce, with list as below.
- Cellulose/Metallized Cellulose/PLA+PBAT Film
- Cellulose/Metallized Cellulose/PBS Film
Fully Recyclable Mono Materials
Compared with the high cost of compostable foil materials, fully recyclable materials sachets, and rolls are flooding the market for lightweight product packages in the market at much lower prices. Mono materials packages mean each layer of the multi-layer foil is made of the same resin, which can be easily processed in the human recycling system and reused for other applications. This recyclable materials sachet largely reduces the rate of plastic polymer film packages ending in landfills.
Nowadays, we have developed some spout pouches based on single resin film materials, that can be found good application for chilli sauce products. Limited to the mechanical strength for current materials, the maximum volume for these recyclable pouches should be control under 250 ml.
Ok, let’s end here, you may reach us if you have any questions, nice day.
