In the supermarket, we often see mini bags with three-side seals for sauces. Many people would like to buy bags directly and then seal them, but this kind of mini bag is not in the form of a bag. The sauce is manually filled and then sealed, which will reduce efficiency and increase labor costs. Therefore, they are generally shipped in the form of packaging film, and then packaged and sealed by machines. So, what are the characteristics and advantages of this kind of mini sauce bag formed after sealing? Let's take a look together!
Features
1. Small and portable: The mini size is suitable for carrying and use, which is convenient for consumers to enjoy sauces on different occasions.
2. Three-side sealing: Provide good sealing, prevent sauce leakage and external contamination, and maintain the freshness and quality of the sauce.
3. Diverse materials: The packaging film can be made of different materials, such as plastic, composite film, etc., to meet the packaging needs of different sauces.
4. Easy to store: It can be neatly placed on shelves or in drawers to save space.
5. Strong printability: exquisite patterns, brand logos and product information can be printed on the surface of the bag to improve the attractiveness and recognition of the product.
Advantages
1. Good preservation effect: strong sealing performance, which can effectively extend the shelf life of the sauce.
2. Easy to print: exquisite patterns and text can be printed on the packaging film to improve the attractiveness and recognition of the product.
3. Low cost: Compared with other packaging forms, the production cost of the three-side sealed mini sauce packaging film is relatively low.
Application scenarios
1. Catering industry: It can be used for sauce packaging in restaurants, fast food restaurants and other places, which is convenient for customers to take.
2. Home use: It is suitable for families to buy small packages of sauces, which is convenient for storage and use.
3. Travel: The portable mini packaging film is suitable for use in travel, picnics and other occasions.
In short, the three-side sealed mini sauce packaging film has been widely used in the field of sauce packaging due to its small size, good sealing and low cost.
What should we pay attention to when choosing packaging materials for sauces?
What are the common materials?
1. Plastic materials: Common ones include polyethylene (PE), polypropylene (PP), etc. These materials have good flexibility, water resistance and chemical stability, and can effectively protect the sauce.
2. Composited materials: Made of multiple layers of films of different materials, such as plastic and aluminum foil. This material has better barrier properties, which can prevent the influence of oxygen, moisture and light on the sauce and extend the shelf life of the sauce.
The following aspects can be considered when choosing a suitable material for a three-side sealed bag for sauces:
Barrier properties
1. Oxygen barrier: The ingredients in the sauce may react with oxygen and cause deterioration. Choosing materials with good oxygen barrier properties, such as aluminum foil composite film or high barrier plastics, can extend the shelf life of the sauce.
2. Moisture barrier: Sauces usually contain a certain amount of moisture, and it is necessary to choose a material that can effectively block moisture penetration to prevent the sauce from getting damp and deteriorating. Plastic materials such as polyethylene (PE) and polypropylene (PP) have certain moisture barrier properties, but for sauces with high moisture content, composite films may be required.
3. Fragrance barrier: Some sauces have a strong fragrance, and it is necessary to choose materials that can block the fragrance to maintain the flavor of the sauce. Aluminum foil composite films and some special plastic materials can provide better fragrance barrier properties.
Chemical resistance
The sauce may contain acid, alkali, salt and other ingredients, and it is necessary to choose materials with good chemical resistance to prevent the packaging material from being corroded or dissolved. Plastic materials such as polyethylene (PE) and polypropylene (PP) have good tolerance to most chemicals, but for some highly corrosive sauces, more corrosion-resistant materials such as polyvinylidene chloride (PVDC) or special composite materials may be required.
Strength and toughness
1. Puncture resistance: Sauces may be squeezed and punctured by external forces during packaging, transportation and storage, and materials with good puncture resistance need to be selected to prevent the packaging from breaking. Aluminum foil composite film and some high-strength plastic materials have good puncture resistance.
2. Tensile strength: Packaging materials need to have a certain tensile strength to withstand the tensile force during filling and transportation. Plastic materials such as polyethylene (PE) and polypropylene (PP) have good tensile strength, but for some heavy sauces, thicker materials or reinforced composite materials may be required.
3. Toughness: Packaging materials need to have a certain toughness to prevent cracking at low temperatures or impact. Some plastic materials, such as polyethylene (PE) and polypropylene (PP), have good toughness, but may become brittle at low temperatures. For sauces that need to be used in low temperature environments, materials with better low-temperature toughness, such as polyvinyl chloride (PVC) or special composite materials, can be selected.
Safety
1. Food contact safety: Select materials that meet food contact safety standards to ensure that the sauce will not be contaminated by packaging materials. Common food contact safety materials include polyethylene (PE), polypropylene (PP), polyester (PET), etc.
2. Environmental protection: Consider the environmental protection of packaging materials and choose recyclable, degradable or less environmentally friendly materials. Some new environmentally friendly materials, such as biodegradable plastics and recyclable composite materials, are gradually being used in the field of sauce packaging.
Cost
The prices of sauce three-side sealed bags of different materials vary greatly, and it is necessary to choose the right material according to the product positioning and cost budget. Generally speaking, the prices of aluminum foil laminated films and high barrier plastic materials are higher, while the prices of ordinary plastic materials such as polyethylene (PE) and polypropylene (PP) are relatively low.
In summary, the selection of suitable sauce three-side sealed bag materials requires comprehensive consideration of factors such as barrier properties, chemical resistance, strength and toughness, safety, and cost. When choosing materials, you can consult professional packaging material suppliers and make choices based on the characteristics and needs of the sauce.
