When it comes to packaging essential food ingredients and products, the selection of appropriate packaging materials is crucial to ensure product integrity and consumer safety. Among various packaging solutions, Sewn Open Mouth PP Bags (often referred to as Sewn Open Mouth Sacks, Open Mouth Bags, or SOM Bags) are highly favored due to their durability, versatility, and cost-effectiveness. These bags are commonly used for packaging food raw materials such as flour, sugar, spices, flavorings, agricultural products, and additives.
In this article, we will explore the benefits of Sewn Open Mouth Bags, with a specific focus on their use in food packaging. We will also discuss key considerations such as load-bearing capacity, labeling requirements, and the necessary certifications for food-grade packaging. Additionally, we’ll examine the role of other variants like Block Bottom Bags and Bottom Open Mouth Bags in meeting the diverse needs of food packaging.
Advantages of Sewn Open Mouth Bags in Food Packaging
Sewn Open Mouth Bags are a popular choice for many industries, especially in the food sector, because of their superior performance in terms of strength and functionality. These bags are typically made from woven polypropylene (PP), a durable and lightweight material known for its high tensile strength. This makes them ideal for packaging heavier loads, especially for bulk food items like grains, flour, and sugar.
Sewn Open Mouth Bags are available in a variety of sizes and customizations, making them suitable for different types of food products. For instance, Sewn Open Mouth Sacks with reinforced seams can be used to carry heavier loads, while lighter bags may be ideal for products such as spices or powdered additives.
Common Applications of Sewn Open Mouth Bags in Food Packaging
Sewn Open Mouth Bags are used to package a wide range of food products, including:
- Flour and grains: These items are often packaged in Sewn Open Mouth PP Bags for ease of transport and storage.
- Sugar: The strong fabric of these bags ensures that sugar is well-contained during transportation and does not spill.
- Spices and flavorings: The bags provide an airtight seal to preserve the freshness of spices.
- Agricultural products: Items such as dried fruits, seeds, and vegetables are typically packaged in these bags to protect them from contamination.

Load-Bearing Capacity of Sewn Open Mouth Bags
The load-bearing capacity of a packaging bag is a critical factor, especially when dealing with heavy food products. In the case of Sewn Open Mouth Sacks, the strength of the woven polypropylene fabric is reinforced through the sewing process, which enhances the bag’s ability to hold heavy weights.
- Standard load-bearing capacity: A typical Sewn Open Mouth Bag can carry between 10 to 50 kilograms (22 to 110 pounds) depending on its size and reinforcement.
- Heavy-duty variants: For larger and more demanding applications, such as flour or bulk sugar packaging, Sewn Open Mouth Bags can be customized to handle even heavier loads, sometimes exceeding 100 kilograms (220 pounds).
The choice of load-bearing capacity will depend on the specific food item being packaged and its transportation needs. For example, in agricultural packaging, heavier Block Bottom Bags may be more appropriate as they offer a sturdy base for stacking, while lighter Bottom Open Mouth Bags may be used for smaller, more delicate food items.

Labeling Requirements for Food-Grade Packaging
When it comes to food-grade packaging, labeling is an essential component to ensure consumer safety and regulatory compliance. For Sewn Open Mouth Bags used in food packaging, the labeling must meet several requirements, including:
- Product Information: Clear labeling of the contents, weight, and ingredients is required. This helps consumers identify the product and understand any potential allergens or other safety considerations.
- Manufacturer Details: Packaging should include information about the manufacturer or distributor to provide traceability in case of recalls or product issues.
- Certification Labels: Food packaging bags must often display certifications like FDA Approval or ISO Certification to verify that the bags are safe for contact with food.
Additionally, Sewn Open Mouth Bags may also feature specific labels or designs for branding purposes. This is an advantage for businesses that want to build brand recognition while ensuring the integrity and safety of their food products.
Food-Grade Certifications and Compliance
For any packaging used in direct contact with food products, ensuring compliance with regulatory standards is essential. Sewn Open Mouth Bags intended for food packaging must meet various food-grade certifications to ensure they do not contaminate the product or compromise its safety. Key certifications include:
- FDA Certification: The Food and Drug Administration (FDA) ensures that materials used in food packaging are safe for direct contact with food products.
- BRC Global Standards: The British Retail Consortium (BRC) certification ensures that packaging manufacturers adhere to high standards of hygiene, quality, and safety for food products.
- ISO Certification: ISO 22000 is a food safety management standard that guarantees that the packaging does not introduce harmful substances or allergens into the food.
Without these certifications, packaging could be deemed unsafe for use in the food industry, leading to potential product recalls or customer dissatisfaction.
Other Packaging Options: Block Bottom Bags and Bottom Open Mouth Bags
While Sewn Open Mouth Bags are commonly used in food packaging, there are other variants that provide additional benefits, especially when it comes to stacking and stability during storage and transport. Two popular alternatives are Block Bottom Bags and Bottom Open Mouth Bags.
- Block Bottom Bags: These bags feature a flat, square bottom that provides greater stability and allows for more efficient stacking. They are ideal for packaging products like grains, flour, and rice, which require precise stacking and minimal space.
- Bottom Open Mouth Bags: These bags are similar to Sewn Open Mouth Bags but have a bottom opening that can be closed with a stitch or seal after filling. This option offers convenience for products that require fast packaging.
