模内标签之综述

随着商业的不断发展,消费者和商家都越来越注重商品的外观包装,而精美的商品标签无疑会提高商品的档次,使得商品更具有吸引力。一般来说,商品标签可分为如下几类：压敏标签、收缩标签、胶粘标签、模内标签等等。其中,模内标签作为塑料容器的一种新型装潢方式,其具有的优点已引起很多行业如：医药、食品、日化、化妆品以及玩具和饮料等的重视,使得模内标签代替传统的压敏标签、收缩标签、胶粘标签等成为标签发展的一个趋势。许多著名公司如雀巢、宝洁、金伯利、联合利华等都积极支持采用模内标签。那么,什么是模内标签,模内标签又有那些优点呢,下文将为你一一介绍。

THE EFFECT of AGE ON the GASTIGHTNESS of ISO FREIGHT CONTAINERS

For many transport applications, it is desirable to limit the interchange of gas between the atmospheres inside and outside a container. Such applications include the transport of produce prone to moisture uptake, incontainer fumigation and controlled- or modified-atmosphere transport, either with or without refrigeration. In this study, the steady-state pressure test was used to measure the gastightness of 143 containers with ages ranging up to eight years. the survey included general-purpose containers of steel, glass-fibre reinforced-plywood and aluminum-panel construction and bulk and refrigerated containers. Within each type of container, the gastightness varied over a wide range, but appeared to depend more on the type of construction than on age. the survey shows that well-constructed containers can retain high levels of gastightness at ages of up to 8 years, and presumably throughout their service lives.

Decreasing Lipid Oxidation in Soybean Oil by a UV Absorber in the Packaging Material

The stability and effectiveness of Tinuvin 326^TM, a UV absorber, dispersed within the regrind layer of coextruded, multilayered, polypropylene-based containers to protect packaged, bleached soybean oil from photooxidation was investigated. The level of Tinuvin 326 in the containers was determined by using high pressure liquid chromatography (HPLC) and UV spectrophotometric methods. No loss of Tinuvin 326 from the containers was observed over a 42-day storage period at 21 and 35°C, respectively. The migration of Tinuvin 326 from the containers to the oil stored at 35°C was greater than at 21°C. Migration levels at both temperatures, however, were too low to notably reduce Tinuvin 326 levels in the containers. Bleached oil in containers with 0.3% Tinuvin 326 underwent less photooxidation than oil in containers with no Tinuvin 326 when exposed to fluorescent light at 21 and 35°C for 35 days.     

A survey of styrene monomer levels in foods and plastic packaging by coupled mass spectrometry—automatic headspace gas chromatography

An extensive UK survey of styrene monomer levels in styrene based plastic packaging materials and their contained foods (133 samples) has been carried out, examining a wide range of retail foods of different brand names and including yogurts, creams, salads, coleslaws, soft cheeses, margarines, hot and cold beverages from dispensing machines, spreads, fresh and cooked meats, candied fruits, fresh strawberries, and take-away ‘fast’ foods. Analysis by headspace gas chromatography of styrene levels in the plastic containers showed levels of monomer ranging from 16 to 1300 mg kg^?1 although the majority of containers (73%) had styrene levels in the range 100–500 mg kg^?1 and only five plastic tubs had levels exceeding 1000 mg kg^?1. Analysis of the food contents of the plastic containers by automated headspace gas chromatography with single ion monitoring mass spectrometric detection showed levels of the monomer ranging from < 1 μg kg^?1 to 200 μg kg^?1, although the majority of foods (77%) had styrene levels below 10 μg kg^?1, and 26% of the total number analysed had levels below 1 μg kg^?1.     

Origins and levels of post pasteurization contamination of milk in the dairy and their effects on keeping quality

Bacterial post pasteurization contamination with psychrotrophic Gram-negative rods (GNR) was measured in commercial milks before and after transfer to retail containers. The tanks of pasteurized milk feeding the filling units contaminated milk less often (39% of samples) but usually at a higher level than the filling units (92% of samples). The number of GNR present had a considerable influence on the shelf life of milk, and the range found in commercially pasteurized milk was reflected in a wide range of shelf lives.     

Serial disinfection with heat and chlorine to reduce microorganism populations on poultry transport containers

A prototype system for the cleaning and decontamination of poultry transport containers was previously developed and evaluated as a means of eliminating foodborne pathogens entering poultry processing plants. While decontamination of the containers once with the use of either hot water (up to 70 degrees C) or sodium hypochlorite (up to 1,000 ppm) resulted in significant reductions in the numbers of coliforms and the elimination of small numbers of Salmonella, complete removal of pathogens was not attained. Therefore, the present study was conducted to determine whether repeated decontamination of the same containers could eliminate coliforms and Salmonella consistently. Individual five-tier containers consisting of galvanized steel frames and fiberglass floors were identified (n = 6) and decontaminated once per day for five consecutive days after being used to haul broilers from farms to the processing plant. Two types of containers were tested in this study: one had previously been used for broiler transportation, and the other had new floors. After each transport, the containers were first precleaned with a cleaning agent using a high-pressure jet (6,094 kPa) to remove debris and to loosen biofilms from surfaces. The containers were then immersed in an aqueous solution of 1,000 ppm of sodium hypochlorite at 70 degrees C for 2 min. Samples obtained from the container surfaces before and after each cleaning and decontamination were analyzed to obtain coliform and Salmonella counts. Coliforms were completely eliminated from both types of containers following one decontamination treatment. Because no Salmonella were detected on the containers, the effect of decontamination in the elimination of Salmonella was not determined. Similar treatments on five successive days also resulted in poultry transport containers that were essentially free of Salmonella and coliforms. This decontamination system involving a combination of heat and sodium hypochlorite can be used as a standard method for cleaning poultry transport containers in the poultry industry. It is recommended that such containers be cleaned after each use to avoid the potential risk of a buildup of significantly higher loads of pathogenic microorganisms and their biofilms.     

Identification of organic contaminants in disposable aluminium foil containers

A series of disposable aluminium foil containers designed for cooking and packaging foods and available on the Italian market were investigated. Using different analytical techniques (near infrared (NIR), High Resolution Gas Chromatography (HRGC), gas chromatography/mass spectrometry (GC/MS)), organic substances used as lubricants in the manufacturing of the containers were detected on the aluminium layer in contact with the food. These contaminants were not mineral hydrocarbon fractions used for the shaping of can lids and bodies, but had an organic structure identifiable as esters derived by synthesis between fatty acids C8 and C10 with glycerine, and between C16 and C18 with butyl alcohol. Mixtures of higher esters were also identified as contaminants. Twelve samples were analysed, and the total amount of contaminant substances was found to range from 900 to 1200 µg dm^-2. It is recommended, for safety and compliance with European Community (EC) Regulation No. 1935/2004 (27 October 2004), that the use of aluminium foil containers be subject to appropriate regulation concerning substances adopted for technological purposes.     

Postharvest shelf life extension of blueberries using a biodegradable package

Small berries are commonly packaged and sold to consumers in vented petroleum-based clamshell containers. Biodegradable and compostable packages may be used as an alternative package to reduce waste generation and landfill disposal. In addition, the current clamshell container design does not allow the development of a modified atmosphere that could prolong berry shelf life. Thus, in this study, a non-ventilated biodegradable container was evaluated as a possible alternative to the containers normally used in commercial distribution of small berries. To determine the potential of biodegradable containers for small berries, highbush blueberries were packaged in polylactide (PLA) containers and stored at 10 °C for 18 days and at 23 °C for 9 days. Commercial vented clamshell containers were used as controls. Physicochemical and microbiological studies were carried out in order to compare the efficacy of both packages. Results showed that the PLA containers prolonged blueberry shelf life at different storage temperatures.
