Ingenious Uses of the Handle on the Rice Bag (1)

Ingenious Uses of the Handle on the Rice Bag (1)

When we buy rice at the supermarket, we notice that the rice bags all have a handle. Sometimes after the rice is finished, the bag is just thrown away. Stop! Removing it has another great use! It’s very helpful. 1. Plastic Bag Handle Carrying many plastic bags can be painful and tiring, and every time you leave the supermarket, it’s a headache. The rice bag handle comes in handy! Remove it and wrap the plastic bags around the handle. No matter how many you carry, it won’t hurt your hands. 2. Storage for Washbasin The washbasin at home takes up a lot of space, and hanging it directly on a hook doesn’t work. Remove the rice bag handle, stick it on the edge of the basin, then hang it on the hook. It won’t fall off no matter what.

Introduction to Stand-up Spout Pouches

Introduction to Stand-up Spout Pouches

Stand-up spout pouches are a relatively novel packaging form, with the greatest advantage over common packaging types being portability; stand-up spout pouches can be conveniently placed into backpacks or even pockets, and they reduce in volume as the contents decrease, making them easier to carry. They have advantages in enhancing product grade, strengthening shelf visual effects, being lightweight to carry, convenient to use, preserving freshness, and being resealable. Stand-up spout pouches are laminated from PET/foil/PET/PE structure layers, and can also come in 2-layer, 3-layer, or other specifications depending on the product being packaged. Oxygen barrier layers can be added as needed to reduce oxygen permeability.

Application of suction nozzle bags

Application of suction nozzle bags

Stand-up pouch with spout packaging is mainly used in products such as juice beverages, sports drinks, bottled drinking water, suckable jelly, and condiments. Besides the food industry, its application in products like detergents, daily cosmetics, and pharmaceuticals is also gradually increasing. The stand-up spout pouch is more convenient for pouring or sucking out contents, and it can be resealed and reopened repeatedly. It can be considered a combination of a stand-up pouch and a regular bottle mouth. This type of stand-up pouch is generally used in daily necessities packaging, for holding liquids, colloids, and semi-solid products such as beverages, shower gel, shampoo, ketchup, cooking oil, and jelly.

Packaging Prospects of Suction Nozzle Bags

Packaging Prospects of Suction Nozzle Bags

Currently, the main forms of soft drink packaging on the market are PET bottles, composite aluminum foil packs, and cans. In today's increasingly homogenized competition, packaging improvements are undoubtedly one of the powerful means of differentiated competition. Stand-up spout pouches combine the resealability of PET bottles and the fashionability of composite aluminum foil packs, while also offering printing performance advantages that traditional beverage packaging cannot match. Due to the basic shape of stand-up pouches, the display area of spout pouches is significantly larger than that of PET bottles and better than non-standing packages like Tetra Pak pillow packs. Of course, since spout pouches fall under flexible packaging, they are currently not suitable for carbonated beverages.

Production Requirements for Stand-up Spout Bags

Production Requirements for Stand-up Spout Bags

The stand-up spout bag consists of two parts: the spout and the stand-up bag. It is a type of soft packaging bag with a horizontal support structure at the bottom and a spout at the top or side. Its production requires high standards; if not properly controlled, defective products may result, leading to issues such as bag inflation, bag breakage, and leakage during use. The production of stand-up spout packaging bags mainly involves several steps: design, plate making, printing, lamination, curing, slitting, and bag making. In this issue, we will focus on the key points to note in lamination and bag making. 1. Selection of Lamination Materials 1. Outer layer: The outer layer is the substrate material. Commonly used substrate materials for stand-up bags in the market, besides ordinary OPP for slitting, include high-strength, high-barrier materials such as PET and PA. For packaging solid products like dried fruits, ordinary materials such as BOPP and matte BOPP can be used; for packaging liquids, PET or PA materials are generally selected. 2. Middle layer: The middle layer is generally chosen for its high strength and high barrier properties. Additionally, the surface tension of the middle layer material must meet lamination requirements and have good affinity with the adhesive. Therefore, materials such as PET, PA, VMPET, and aluminum foil are commonly used. 3. Inner layer: The inner layer is the heat-sealing layer, typically made of PE, CPE, CPP, or other materials with strong low-temperature heat-sealing performance. The surface tension of the laminated side must meet lamination requirements, but the heat-sealing surface tension must be below 34 mN/m and possess good anti-contamination, anti-static, and heat-sealing properties. 2. Requirements for Bag Making Process 1. Heat-sealing temperature: When setting the heat-sealing temperature, factors to consider include the characteristics of the heat-sealing material, film thickness, the number of heat-sealing presses, and the size of the heat-sealing area. Generally, if the same area is pressed multiple times, the heat-sealing temperature can be set slightly lower. 2. Heat-sealing pressure: Appropriate pressure must be applied during heat sealing to promote adhesion of the heat-sealing materials. However, the pressure must be controlled carefully; excessive pressure can cause molten material to be squeezed out, affecting the flatness of the bag and the heat-sealing effect, thereby reducing heat-sealing strength. 3. Heating method: The heating method of the heat-sealing knife during bag making can be divided into single-sided heating and double-sided heating. Double-sided heating is more efficient and practical than single-sided heating. The main issues encountered in the actual production of stand-up spout bags lie in these two aspects. Therefore, how to select materials properly and adopt the best process operation methods plays a decisive role in improving the overall quality of stand-up spout bags.
