The package puff pastry juice packaging process is divided into three stages: preliminary work, sterilization treatment and package puff pastry packaging
Preliminary work for packaging includes Select composite materials, design brick-shaped cartons and box structure drawings, and carry out decoration design, and then deliver it to a professional packaging material factory for printing according to the patterns, text, and colors of the decoration design, indentation and cutting according to the structural design, and finally roll The web material is transported to the packaging factory.
The package puff pastry environment of the operation workshop must be sterilized before and after packaging, the air entering the room needs to be purified, and the air pressure in the workshop environment must be kept slightly higher than the outside atmospheric pressure to prevent outside air from entering the workshop and reduce the invasion of bacteria and dirt during the packaging stage
The main processes of package puff pastry are:
(1) Filling Filling is the most important process in the entire package puff pastry packaging process. It consists of multiple work steps and is completed on a filling machine.
- ①Paper roll loading. Use a special trolley to push the paper roll to the machine, and use an automatic paper splicer. When the old paper roll is almost used up, the new and old paper rolls can be connected without stopping the machine. The paper roll 1 is fed by a motor-driven feed roller 3, and the floating roller 2 can start or stop the feed roller 3. The paper tape travels to 4 places to print the production date and presses horizontal creases.
- ②Sealing. In order to prevent leakage after heat sealing on the back of the sterile carton, tape should be used to further seal the heat sealing area. The specific method is to use a sealing applicator to stick half of the 8mm-width PP tape on the inner edge of the wrapping paper, and the other half is bonded to the other edge of the wrapping paper during vertical sealing to obtain a tight and strong seal.
- ③Sterilization. Before filling, the package puff pastry packaging paper is soaked in a hydrogen peroxide (hydrogen peroxide) tank for sterilization.
- ④Dry. Use a pair of squeeze rollers 7 to squeeze out the hydrogen peroxide on the wrapping paper. At the same time, the air curtain 8 is used to spray out high-temperature sterile air of 140~150°C to dry the hydrogen peroxide that remains on the surface of the packaging paper after extrusion and decompose it into harmless water vapor and oxygen. At this time, the high-temperature air can also enhance the sterilization efficiency of the new ecological oxygen and kill some remaining bacteria.
- ⑤Heat sealing and filling. The package puff pastry packaging paper is formed into a tube through four guide rollers and the former. At this time, the edges on both sides of the packaging paper overlap by about 8mm. The vertical sealing device 10 continuously heat-seals the PE films inside and outside the packaging paper at the overlap, and pre-pasted The PP tape on the inner edge is firmly bonded; at the same time, the juice that has been sterilized and transported from the sterile pipe is poured into the paper tube through the filling device 9. In order to meet the requirements of aseptic packaging, the filling pipe end must always be Drown in juice.
- ⑥Fix the volume, press the edges, and seal horizontally. The device consists of two pairs of claws connected up and down alternately. When working, it swings up and down, in and out, and seals the juice with a capacity of 250mL in a paper cavity with a rectangular cross-section. The end surface of the claw is equipped with a heat sealing and cutting device. Two adjacent cartons are heat-sealed transversely with the help of two layers of PE films in the package puff pastry packaging paper. The heat-sealing width is about 16mm. Use a cutting knife to cut it into There are two parts: the upper half serves as the top seal of the previous carton, and the lower half serves as the bottom seal of the subsequent carton. In the figure, there is a sealed sterile area within the dotted line box, which can further ensure that the filling work can be carried out safely and reliably in a small sterile environment.
- ⑦Fold corners. The side corners of the top and bottom of the small package are folded to the side and bottom respectively in the brick-shaped folder, and 160°C high-temperature steam is sprayed on the bottom and side at four positions to make the top and bottom corners stick to the sides and the bottom sides. Glue the side corners to the bottom. The bottom side of the carton is facing up in the folder, and the top side of the finished product is facing up when it is discharged from the folder to the conveyor belt.
(2) Straw attached Straws are made by professional factories for the convenience of consumers to drink. They are made of polyethylene plastic with a length of 115mm and a diameter of 4mm. It is package puff pastry in two layers of polyethylene plastic film suitable for its length and sealed side by side, ready for use. The straws are stuck on the diagonal line on the back of the sterile packaging carton, which is completed by a special tube sticking machine. The post-packaging work mainly includes:
- (1) Install corrugated pallets and perform heat shrink packaging. The quantities can be freely combined according to sales needs. Usually there are medium packaging methods such as 2×3, 3×4, 4×6 or 3×9. The shape of 3×9 is shown in Figure 8-7.There are two stations on the heat shrink package puff pastry packaging machine. First, the packaging unit consisting of the pallet and the product is pre-packaged with flat film. After the PVC heat shrink film wraps the pallet, the sealing and cutting mechanism drops to heat seal and seal the other side. Cut at the same time; wrap the pre-packaged The package is placed on the conveyor belt and sent into the hot aisle. The hot air at 150°C is used to shrink the PVC film. After cooling, it is removed from the conveyor belt to form a shrink-wrapped package.
- (2) When the collective packaging aseptic packaging cartons are transported in containers, they need to be packaged using stretch packaging 5. Inspection of juice aseptic packaging Aseptic fruit juice packages are subject to online inspection. After the initial adjustment of the filling machine, before tube sticking, 2 boxes will be randomly inspected every 10 minutes to check the molding, sealing and pasting quality and filling capacity. After normal operation, 2 boxes will be randomly inspected every 30 minutes, and the inspection contents are the same.
Drugs are two special commodities that are related to human life and safety, so their effectiveness and safety must be strictly guaranteed. The Drug Safety:
Quality Management Practices (GMP) proposed by the World Health Organization (WTO) is to achieve comprehensive quality management of drugs from raw materials entering the factory to final delivery. Among them, the packaging operating procedures of pharmaceutical factories, packaging sites, and packaging The personnel, package puff pastry packaging equipment, packaging materials, packaging equipment, packaging markings, etc. all have clear regulations and strict requirements. In short, pharmaceutical packaging must have functions such as safety, reliability, good protection, easy processing, sales promotion, economical, convenient use, and information transmission. 1. Packaging requirements for various drugs
There are many types of medicines, and the technical requirements for package puff pastry include:
① The impact of external factors on medicine bottles. Drugs are extremely susceptible to physical, chemical, microbial and climatic conditions. For example, they are easily oxidized in the air and infected with bacteria. They are easy to decompose and change color when exposed to light. They are easily decomposed and deteriorated when exposed to heat. They are easy to volatilize and soften when heated. As a result, the drugs lose their efficacy and sometimes not only do they not work. Treating a disease can actually cause disease and endanger life safety. Therefore, regardless of the shape, structure, decoration design and selection of packaging materials for pharmaceutical packaging, we must first consider its protective performance, that is, maintaining the efficacy of the drug. The average validity period of medicines is 2 years, and some can reach more than 3 years. Therefore, package puff pastry should also ensure that the ingredients of the medicines are stable during the validity period and will not deteriorate. Different dosage forms of medicines deteriorate in different ways.
Solid drugs such as tablets and powders are susceptible to moisture. When temperature and humidity change, their shape and quality will gradually change. For example, after sugar-coated tablets become damp, the surface will deliquesce and cracks will appear over time, which will reduce the content of the main ingredients of the drug. The effect is reduced. Another example is the sticking phenomenon of powders and granules after getting wet, which also reduces the efficacy and quality of the medicine.
Although medicines such as liquids or injections are not susceptible to moisture, they are prone to oxidation when in contact with oxygen in the air, which can also change the main components of the medicine and cause discoloration or precipitation; some medicines are also susceptible to contamination by bacteria, fungi, and yeast. Deteriorates, completely loses its efficacy and becomes a waste product.
Viscous drugs such as ointments will soften, or undergo oxidation and color changes when exposed to temperature changes and light exposure.
Drug packaging requirements. First of all, the patient’s psychological state and requirements must be taken into consideration, and sufficient information should be included to enable buyers to understand the ingredients and manufacturing background of the drug, its exact efficacy on the disease, and how to take it. The styling design should reflect a sense of security and trust. At the same time, it should be easy to use, carry and store, and it should also be considered to facilitate packaging automation to improve productivity. Table 8-6 shows the classification of pharmaceutical dosage forms and the package puff pastry packaging forms used for reference.
According to the drug circulation environment, such as temperature, humidity, oxygen, light, etc., as well as the characteristics of the drug dosage form, appropriate packaging processes and materials should be selected for protective packaging design. For example, for medicines that are easily affected by moisture, moisture-proof packaging materials need to be used for moisture-proof packaging design; for medicines that are unstable when exposed to light, light-shielding materials should be used.
package puff pastry materials are pulp products made from paper pulp (or waste paper pulp) as the main raw material, and the fibers are formed, compacted and dried on a drainable metal mold net. Our country began producing pulp molded products in the early 1980s, and they were first used in buffer packaging for the transportation of fragile commodities, such as egg trays. At present, its application scope has been expanded to transportation packaging, such as pulp molded pallets, buffer structural parts of some mechanical and electrical products, etc. When producing pulp molded products, if supplemented by bleaching enhancement, coloring, coating and other processes, the performance and appearance of the molded products can be further improved, and they can be used for sales packaging of food, etc. As people’s environmental awareness increases, pulp molded products may become the best alternative to difficult-to-handle materials such as foam plastics.
