The following analysis starts from the core issues of the industry and combines data and cases.<\/h2>\n<h2>Sources and Further Reading<\/h2>\n<p>The material safety and food-contact claims cited in this article are drawn from the following primary regulatory and industry sources. Each entry links to the original document.<\/p>\n<ul>\n<li><a href=\"https:\/\/www.ecfr.gov\/current\/title-21\/chapter-I\/subchapter-B\/part-177\" target=\"_blank\" rel=\"noopener\">FDA 21 CFR 177 &mdash; Food Contact Polymer Standards<\/a><\/li>\n<li><a href=\"https:\/\/eur-lex.europa.eu\/eli\/reg_impl\/2011\/10\/oj\" target=\"_blank\" rel=\"noopener\">EU Regulation 10\/2011<\/a><\/li>\n<\/ul>\n<h3 class=\"wp-block-heading\">I. Plastic Food Packaging Safety and Material Problems<\/h3>\n<p>Q1\uff1aIs plastic food packaging safe? Will heating release harmful substances?<\/p>\n<p>A1: Food-grade plastic packaging that meets national standards is safe under normal usage conditions. Make sure to identify the &#8220;For Food Contact&#8221; label and the QS\/Production license number.<\/p>\n<p>Q2\uff1aWhy do some plastic food packaging deform, crack, or turn yellow after just a few uses?<\/p>\n<p>A2\uff1aThis is usually caused by the following reasons:<\/p>\n<ol class=\"wp-block-list\">\n<li>Material aging: Repeated heating, scrubbing, and ultraviolet radiation will accelerate the aging of plastics.<\/li>\n<li>Improper use: PS boxes contain overly hot food, and PP boxes are overheated (such as frying oil temperature).<\/li>\n<li>Physical damage: Scratches from sharp objects, drops, and impacts.<\/li>\n<li>Oil penetration: Long-term storage of high-oil foods may cause plastics to swell and become brittle.<\/li>\n<li>Suggestion: Use as per the instructions, avoid extreme conditions, and replace in time when aging is obvious.<\/li>\n<\/ol>\n<p>Q3\uff1aWhat do the numerical labels (such as 5 and 6) on plastic food packaging represent?<\/p>\n<p>A3: This is the plastic recycling label (resin identification code), and it doesn&#8217;t mean that the plastic is safe or that it may be microwaved. Some common ones that are used to package food include:<br \/>1. #5: PP (polypropylene) is a good material for lunch boxes, soup cups, and yogurt cups that can be heated up in the microwave.<br \/>2. #6 PS (Polystyrene): This material is often used to make disposable sushi boxes, fast noodle bowls, and cup lids. Not heat-resistant; hard and brittle.<br \/>3. #1 PET (polyethylene terephthalate): This is a common material used to make clear salad boxes and drink bottles. It is not a good idea to heat or reuse.<br \/>The &#8220;for food contact&#8221; label and material description are still the most important things for safety.<\/p>\n<\/p>\n<h3 class=\"wp-block-heading\">II. Usage and Functional Issues<\/h3>\n<p>Q4\uff1aIs it possible to freeze plastic lunch boxes or soup cups in the fridge?<br \/>A4:&nbsp;It depends on the material and how it is made.<\/p>\n<p>1. PP (#5) material is normally kept in the fridge or freezer, but it can get brittle when it&#8217;s cold. Don&#8217;t drop it or bump it.<\/p>\n<p>2. PS (#6) material is very fragile and can break when it freezes. We don&#8217;t suggest it.<br \/>Take care with the sealing: freezing can change the shape of the lid and impair the sealing. It is best to leave some room for things to grow.<\/p>\n<p>Q5\uff1aWhy does it seem like the lid is stuck and hard to open when you use a plastic soup cup or bowl to hold hot soup?<br \/>A5\uff1aThis is a physical phenomenon (negative pressure), not a problem with the quality.<br \/>Steam comes from hot soup. The steam condenses when it cools down, which lowers the pressure within the cup and makes the lid fit tightly.<br \/>To fix this, either loosen the lid before heating it or rinse the edge of the lid with warm water after it has cooled to break the seal.<\/p>\n<p>Q6\uff1aAre plastic cartons for grilled chicken and fried meals safe? Can oil get into plastic?<br \/>A6: It&#8217;s okay to store things for a short time; however, please note:<br \/>1. Grade for food PP, PET, and other materials don&#8217;t soak up oil very well.<br \/>2. Long-term soaking or being in temperatures that are too high (above 120\u00b0C) may make it more likely that oil will get through. Not a good idea to store for a long time.<br \/>You should let fried dishes cool down before putting them in plastic cartons.<\/p>\n<\/p>\n<h3 class=\"wp-block-heading\">III. Environmental Protection and Recycling Issues<\/h3>\n<p>Q7\uff1aWhat does it mean for plastic packaging to be &#8220;degradable&#8221;? Can it go straight into the trash can in the kitchen?<br \/>A7\uff1a<\/p>\n<p>1. Most &#8220;degradable&#8221; plastics need to be composted in an industrial setting, not at home!<br \/>Most food packaging on the market right now is made of either regular plastic (PP\/PS\/PET) or 2<\/p>\n<p>2. Compostable plastic (which must be clearly labeled).<br \/>Compostable plastics: They must be handled in factories that meet certain temperature, humidity, and microbiological conditions, and they cannot be thrown away or composted at home.<\/p>\n<p>3. If there are no industrial composting facilities nearby, it should be thrown away with other trash and non-recyclable materials. However, if there are local collection channels, it should be treated differently. Don&#8217;t mix in trash from the kitchen!<\/p>\n<p>Q8\uff1aWhy do I think plastic packaging is becoming more and more common? Is the business using less plastic?<br \/>A8:&nbsp;1. The industry is really looking for ways to utilize less plastic.<br \/>2. Lightweighting is using less plastic in a single product, such as making the walls thinner.<br \/>3. Design optimization: Cut down on extra layers of components and packaging.<br \/>4. Material substitution: Research and development for using renewable materials, recycled materials (rPET), and compostable plastics (there are still cost, performance, and facility issues).<br \/>5. Being a part of the recycling system: Help set up a full recycling system.<\/p>\n<\/p>\n<h3 class=\"wp-block-heading\">IV. Act now to safeguard the environment and keep people safe.<\/h3>\n<p>1. Understand the label and follow the instructions, especially during heating!<br \/>2. Clean and sort plastic well so that it can be recycled more easily.<\/p>\n<p>In today&#8217;s world, plastic food packing is a good choice. We may enjoy the convenience while protecting our health and the Earth if we take the appropriate attitude and think about things logically.<\/p>\n<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Is the this food container microwave-safe?<\/h3>\n<p>Yes.
