Origin of cooperation: First encounter at Canton Fair, official website inquiry and matchmaking   During the 139th Canton Fair, Guangzhou Rosin Packaging Co., Ltd. attracted global merchants to stop and inquire with its professional vacuum packaging solutions and mature production strength. A well known purchaser of 3C electronic parts from Canada, after gaining a deep understanding of Rosinpack's technological advantages in the field of precision electronic vacuum packaging at the exhibition site, submitted a formal inquiry through the official website, clearly expressing their intention to cooperate and hoping to customize anti-static, highly adaptable, and recyclable specialized vacuum trays and inner packaging for their high-end 3C electronic parts.   As a company that has been deeply involved in the 3C electronics supply chain for many years, customers have strict requirements for the anti static performance, dimensional accuracy, environmental standards, and batch delivery capability of packaging. After multiple rounds of online technical communication, sample confirmation, and solution optimization in the early stage, the customer team highly recognizes Rosinpack's professionalism and has decided to make a special trip to the Zengcheng production base in Guangzhou for on-site inspection and negotiation of long-term cooperation details. On site factory visit: The full chain strength has been highly recognized by customers On June 5, 2026, the Canadian Director of Electronic Parts Procurement and his team arrived at the Rosinpack production base for a comprehensive on-site inspection.

Types of Plastic Food Packaging and Safety Did you know? Plastic is a surprisingly versatile material with elemental origins. Elements from the periodic table, such as carbon, hydrogen, oxygen, nitrogen and sulfur, are the building blocks for a variety of plastics used to make many of the products we use every day. Some plastics are transparent and durable for use in eyeglasses or safety goggles. Other plastics are strong and lightweight, allowing us to ship more products with less packaging. Plastics can even be bacteria-resistant for use in food packaging and life-saving medical equipment. You don't have to be a scientist to understand the many ways plastics are useful. Plastics are used in many types of food packaging and containers for a variety of reasons – they help protect foods from damage, provides food safety and extends the freshness of foods.   What are the different types of plastics used in food packaging? You may have seen the number 1 through 7 on the bottom or side of a plastic packaging container. This number is the plastic “resin identification code,” also known as the “recycling number.” This number can also provide guidance for consumers who want to recycle plastic containers. Many major types of plastic resins used in packaging (#1 through #7) are recyclable. Most frequently, community recycling programs collect plastic bottles made from PET (#1) and HDPE (#2), but many communities are expanding their programs to collect additional types of plastics. Although most communities instruct residents to recycle by the shape of an item (e.g., bottles, containers, caps, lids), some communities also refer to the resin identification code. If you have questions about which plastics are recycled in your community, see the 2015-2016 Study on Recycling Access and check with your local recycling or solid waste facility. It’s easy to search online.

Egg prices skyrocket, industry competition intensifies, Rosinpack breaks through the low profit dilemma of egg vacuum packaging with technological intelligence In 2026, the global spot price of eggs will continue to rise and break through $35 per kilogram, ushering in a historic profit window for egg chicken farming, with a single kilogram profit of up to $1.2-1.7. In sharp contrast to the booming market in the aquaculture industry, the upstream egg packaging industry is facing an industry inversion dilemma of soaring egg prices and continuous compression of packaging profits: fluctuations in raw material costs, low price competition among peers, shrinking demand for high-end gift boxes, and pressure on the entire industry's thin profits. As a professional manufacturer of food grade PET vacuum packaging, Rosinpack relies on automated production lines, structural optimization research and development, and large-scale centralized procurement price advantages to find a breakthrough path of "technology cost reduction, structural efficiency improvement, and long term strategic cooperation", providing a cost effective integrated solution for egg vacuum packaging for large egg enterprises, fresh food supply chains, and supermarket brands nationwide. 1、 Industry situation: Under the rocket egg market, egg packaging factories are caught in a triple operational embarrassment The recent surge in egg prices during the off-season has completely exposed the structural contradictions in the egg packaging industry chain, and the industry is generally facing triple operational challenges: The pricing of finished products has no say, and a slight increase in price can lead to customer loss The mainstream PET transparent egg boxes and pulp egg trays in the market are severely homogenized, and the competition in the wholesale market is fierce, with a single set of packaging profit of only a few cents. The sensitivity of cost control for farmers and traders has significantly increased, and packaging manufacturers who slightly increase unit prices will immediately receive orders from competitors. Enterprises dare not adjust prices and can only passively digest the pressure of rising costs. Double directional squeezing of raw materials leads to a continuous reduction in profit margins In 2026, the prices of plastic particles, waste paper, and cardboard will fluctuate frequently, and packaging companies will have to bear the rising costs of raw materials and logistics while unable to simultaneously increase the prices of finished products. Under the dual pressure of upstream and downstream, the industry's average gross profit margin will continue to decline, and the survival space of small and medium-sized packaging factories will sharply narrow. The demand for high-end gift boxes has cooled down, forcing brand packaging to be downgraded and downgraded The unit price of bulk eggs has risen synchronously, and consumer consumption is becoming more rational, resulting in a...

Dragon Boat Festival Special     The Dragon Boat Festival falls on the 5th day of the fifth lunar month, featuring exciting dragon boat races and traditional triangular zongzi (sticky rice dumplings).     Zongzi and fancy pastries are top-selling gifts for supermarkets, bakeries and gift brands worldwide. Reliable blister packaging is essential for festive food, which perfectly displays food appearance while protecting products during display, delivery and gifting.       We provide two mainstream custom blister packaging solutions for seasonal food: Custom triangular zongzi blister tray is precisely shaped to fit traditional rice dumplings.

1、 Market background: High temperature heat waves drive rigid demand for edible ice packaging at home and abroad With the normalization of extreme heat weather worldwide, the sales of pre packaged ice cups, bagged edible ice cubes, and high quality ice hockey in domestic convenience stores have doubled year by year; The overseas markets in Europe, America, Australia, and Southeast Asia continue to have a high demand for standardized packaging of ice hockey, square ice, diamond ice, and giant slow melting ice due to the culture of iced coffee, whiskey cocktails, and cocktails, as well as commercial bars, catering chains, and high end hotels. Data shows that the global ice mold and pre packaged ice product market has a compound annual growth rate of over 5.3%. North America is the core consumer market, and pre packaged edible ice alone is directly classified as a food category by the FDA in the United States, with mandatory regulatory requirements for packaging safety, sealing, and low temperature tolerance. The pain points of traditional PE plastic bag packaging, such as easy puncture, water leakage, poor display appearance, and large loss due to ice crushing, are becoming increasingly prominent. Food grade vacuum formed rigid packaging has become an upgraded alternative to commercial pre packaged ice products, retail ready to eat ice cups, and high-quality shaped ice hockey. It has also become a key new product development track for Rosinpack this year. Core requirement breakdown Safety and compliance requirements: ice cubes can be directly consumed, and the packaging must pass FDA 21 CFR and EU 10/2011 food contact certification. It can withstand low temperatures of -20 ℃ without releasing harmful substances; Shortcomings in display appearance: Plastic bags cannot display the transparent ice hockey texture, low recognition of supermarket shelves, and weak premium ability; Insufficient shelf life: Ordinary single layer packaging has fast water vapor penetration, ice cubes are prone to adhesion and rapid melting, and the shelf sales cycle is short; Lack of scene segmentation: Large diameter whiskey ice hockey, block ice, irregular carved ice, single independent packaging, and lack of specialized shaped inner trays for whole box quantitative packaging. 2、 Rosinpack Ice Products Special Blister Packaging Material System Based on the mature hot forming co extrusion technology of the factory, three major material product lines are divided for long-term sub zero freezing and high water vapor environments of ice products, all of which can provide a complete set of export testing reports: 1. Basic universal version: Food grade brand new PET vacuum forming Material: Brand new high transparency PET sheet, no recycled impurities, passed FDA, EU food contact standards, modified formula for anti brittleness at -25 ℃ low temperature, and not easily cracked after repeated freeze-thaw cycles; Advantages: Ultra high transparency, transparent display of ice hockey...
